napi_completion could stop NAPI re-queue only if
returned budget is small than limit budget. WLAN
driver IRQ affinity change would force NAPI complete.
In some cases, RX is in busy loop, RX NAPI could be
queued to more than one CPU NAPI polling list, which
will lead system crash. This change is aimed to make
sure that returned budget is smaller than the limit.

that the version-specific changes are only needed in QDF.

MSI vector number is defined in platform driver, so use platform
driver API to check whether it is in one MSI mode or not.
In case of one MSI vector, interrupt migration needs to be disabled.
This is because when interrupt migration happens, the MSI data may
change. However, MSI data is already programmed to rings during initial
phase and there is no way to know that MSI data is changed during run
time and reprogram again.
If it is in one MSI mode, disable interrupt migration by adding IRQ
flag IRQF_NOBALANCING.

Fix race condition in dispatch interrupt when CE0 interrupt is called
from irq context in one core while it is called from user context in
ring full condition. This case has to be handled using locks since
calling paralelly from multiple contextx is leading to interrupt
getting disabled and tasklet not getting scheduled. This is leading
to interrupt being in disabled state. Also change th diff_time variable
signed integer to handle a case where taklet is scheduled just after
the workaround kicks in leading to diff_time becoming negative.
