qcacld-3.0: Introduce wma_validate_handle()

Browse source 
Introduce wma_validate_handle() with the caller function name
embedded in it to validate the WMA handle and log incase
of error. Calling functions can avoid logging in case
wma_validate_handle() returns -EINVAL. This reduces logging and
thereby memory foot print.
