qcacld-3.0: Add Validation for WMA Handle and PSOC in Wake Event

Browse source 
Currently, the WOW wakeup event handler lacks validation for the
WMA handle and the PSOC pointer within the WMA handle. This omission
can lead to null pointer dereferences in the host.

To address this issue, null pointer checks for both the WMA handle
and the PSOC pointer have been added.
