cnss2: Validate maximum number of memory segments

For WIN use case maximum number of memory segments requested
by FW is increased to 52 in QMI layer. Since CNSS2 driver uses
same QMI header files and message structures the same maximum
number of segment is applicable for CNSS2. It means for memory
allocation, FW can request 52 memory segments to CNSS2 via QMI
indication but local CNSS2 variable which get segment info from
indication supports maximum 32 segments.
To fix it, change CNSS2 array variable size to same as number of
maximum segment supported in QMI layer.

cnss2: get msi_data again after request_irq is called

The reservation mode of interrupts in kernel assigns a dummy vector
when the interrupt is allocated and assigns a real vector when the
request_irq is called. The reservation mode helps to ease vector
pressure when devices with a large amount of queues/interrupts
are initialized, but only a minimal subset of those queues/interrupts
is actually used.
So on reservation mode, the msi_data may change after request_irq
is called, so reads msi_data again after mhi request_irq is called,
and then the correct msi_data is programmed into hardware components.
Without this change, spurious interrupt occurs in case of one MSI
vector.
