qcacld-2.0: Fix potential double free in wma_log_supported_evt_handler

propagation from qcacld-3.0 to qcacld-2.0

In wma_log_supported_evt_handler, events_logs_list in
wma handle is freed if previously allocated. If the
num_of_diag_events_logs exceeds the max size, we exit
from the function early without allocating memory for
events_logs_list. This can result in potential double
free scenario if we receive another DIAG_EVENT_LOG_SUPPORTED
event from firmware.

Fix is to set events_logs_list pointer to NULL after
freeing memory.
