staging: rtl8723bs: fix memory leak on failure path

Browse source

[ Upstream commit abe850d82c ]

cfg80211_inform_bss_frame() may return NULL on failure. In that case,
the allocated buffer 'buf' is not freed and the function returns early,
leading to potential memory leak.
Fix this by ensuring that 'buf' is freed on both success and failure paths.
