[FFmpeg-devel] [PATCH, v2] lavc/qsvenc: Fix the memory leak for enc_ctrl.Payload

frame->enc_ctrl.Payload is malloced in get_free_frame, directly memset
the whole structure of enc_ctrl to zero will cause the memory leak for
enc_ctrl.Payload.

frame->enc_ctrl as a structure will be malloc and init to zero by calling
frame = av_mallocz(sizeof(*frame)), so the memset is redundant and can
be removed.

Can be reproduced by #7830.
