Haihao Xiang a7f24d79b8 lavc/qsvenc_hevc: restore the default gop size 
commit a3c0a3e changed the default settings and expected the runtime can
choose a best value. However the runtime doesn't set a valid gop size
for hevc encoder, hence the output steam is non-seekable, which is
inconvenient to user [1][2]
