lavc/qsvenc: Fix bitrate_limit to allow AVC encode in limited bitrate
MFXVideoENCODE_Query calls CheckVideoParamQueryLike in MSDK and
will determine whether to set param.mfx.TargetKbps to the allowed
minTargetKbps according to the bitrate_limit in extco2 buffer.
Thus q->param.ExtParam must be set before MFXVideoENCODE_Query in case
minTargetKbps is written to TargetKbps by default.
1080P AVC encoding with option "-bitrate_limit 0 -b:v 100k":
