qcacmn: Handle gracefully if scheduler cb is not registered

Currently when firmware crashes during driver load,
message queue handlers for scheduler context are not
registered. While handling the FW down event, driver
posts the message to scheduler queue. Since the queue
handler is not registered, it results in crash.

To address this issue, handle the msg gracefully and
return error in case callback is not registered.

qcacmn: Disable panic for scheduler timeouts

When a scheduler message starts porcessing,we start
the scheduler watchdog timer, and in few cases when the
system get under heavy load processing tasklets
and bottom halves, and the scheduler message is preempted,
its not getting a chance to run and the scheduler watchdog
timer is triggered and it causes a panic.

Since the scheduler watchdog timmer is less than
the kernel RCU timer, were are having scenarios, where
because of the scheduler watchdog panic, the RCU stall is masked.

So in case of scheduler watchdog we wanted to just print
the information about the message being processed by the scheduler
and not panic.

The scheduler watchdog timeout is currently fixed at 10secs.
There are few customer use cases, where the CPU is busy for

the coinfigured watchdog timeout value.

Add a new API to be able to configure this value different than the
default as per the requirement.

qcacmn: Check if the scheduler thread is already flushed

During the module initialization the scheduler thread and the
init thread run in parallel if there is a failure in the error
path, the scheduler thread is not aware and still sending
the messages to firmware resulting in system instability.
So, Disable the scheduler as soon as there is an error in the init path
and the same scheduler thread in the normal existing error path.

If the scheduler_disable is called multiple times the infinite wait
for result will get the init thread struck.

Other changes to conform to this new type include:
1. Cast callback to qdf_mc_timer_callback_t when

2. Cast wlan_serialization_generic_timer_cb to

3. Cast target_if_vdev_mgr_rsp_timer_cb to fit

qcacmn: Unified scheduler watchdog handler implementation

The scheduler watchdog timer handler currently either prints error or
prints error and panics based on CONFIG_SLUB_DEBUG_ON.

Considering the panic through QDF_DEBUG_PANIC is configurable and is
disabled on relevant builds, we can just have one version of the
function and depend on QDF macro for panic and dependency on
CONFIG_SLUB_DEBUG_ON is redundant

Change the default log levels from none to fatal for scheduler.
