qcacld-2.0: Fix OOB write in wma_unified_debug_print_event_handler
propagation from qcacld-3.0 to qcacld-2.0
The routine wma_unified_debug_print_event_handler logs the data from debug
print event handler. The param event data from firmware is copied to a
destination buffer .If the maximum size of the data exceeds or equals
BIG_ENDIAN_MAX_DEBUG_BUF for big endian hosts then possible OOB write will
occur in wma_unified_debug_print_event_handler. For other hosts, OOB read
could occur if datalen exceeds maximum firmware message size
WMI_SVC_MAX_SIZE.
Add check to validate datalen doesnot exceed the maximum firmware msg size
WMI_SVC_MAX_SIZE. Return failure if it exceeds.
Add check to ensure datalen doesnot exceed or equal the maximum buffer
length value for big endian hosts BIG_ENDIAN_MAX_DEBUG_BUF.
Add null termination at the end of the data recieved from the firmware.
