dibusb: fix possible memory leak in dibusb_rc_query()

Browse Source 
commit 1f5ecaf985 upstream.

'buf' is malloced in dibusb_rc_query() and should be freed before
leaving from the error handling cases, otherwise it will cause
memory leak.

Fixes: ff1c123545 ("[media] dibusb: handle error code on RC query")
