INT_MAX may be used to access array 'hif_ext_group->os_irq' of
size 16 in function hif_ipci_irq_set_affinity_hint().

Fix is to add index range check before accessing those arrays.

qcacmn: Fix out of sync OOM work counter

Currently OOM work counter is incremented when schedule_work
is called and counter is decremented when work is scheduled.
But there is possibility of OOM schedule_work is getting called
from tasklet context and worker thread context and resulting
only one time work execution but active work counter being
incremented twice. This scenario may result in OOM work going
out of sync and preventing suspend usecase.

Avoid this by incrementing the OOM active work count only when
work is getting added to global work queue and corresponding count
will be decremented when work handler gets executed.

qcacmn: Force update HP/TP upon delayed register writes

Currently if HP/TP register updates are delayed due to delayed reg
write work not getting scheduled, although driver has processed
the ring completely, hardware would see HP/TP delta and fires an
interrupt based on interrupt threshold configuration until the
HP/TP updates reach the hardware.

When system is heavily stressed, this delay in HP/TP updates would
result in IRQ storm further stressing the system which is bad.
Force update HP/TP to the hardware under such scenarios to avoid
this problem.

Currently doing this just for CE DST SRNGs, this can be scaled to
other SRNGs on need.

qcacmn: Increase soc wake time for ipci devices

Currently for IPCI devices, SoC wake request and release messages
are serialized, i.e., a new request cannot make it to the firmware
unless the current request is completed. In some cases, when system
is heavily loaded, SoC wake request cannot make it to the firmware
due to a previous SoC wake release resulting in a timeout.

Increase the SoC wake timeout to 1 second to avoid this. Since this
is a worst case value, increasing it should be fine.
