From: Rajat Soni <quic_rajson@xxxxxxxxxxx> [ Upstream commit 960412bee0ea75f6b3c2dca4a3535795ee84c47a ] Currently the buffer pointed by event is not freed in case ATH12K_FLAG_UNREGISTERING bit is set, this causes memory leak. Add a goto skip instead of return, to ensure event and all the list entries are freed properly.
