mwifiex: fix error handling in mwifiex_create_custom_regdomain ...
smatch reports:
sta_cmdresp.c:1053 mwifiex_create_custom_regdomain() warn: possible memory leak of 'regd'
Indeed, mwifiex_create_custom_regdomain() returns NULL in the
case that channel is missing in the TLV without freeing regd.
Moreover, some other error paths in this function return ERR_PTR
values which are assigned without checking to the regd field in
the mwifiex_adapter struct. The latter is only null-checked where
used.
Fix by freeing regd in the error path, and only update
priv->adapter->regd if the returned pointer is valid.
