e786e37326 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":

1aec1183f3 avcodec/v4l2_buffers: Fix infinite loop
This part of the code counts the number of planes returned by the v4l2
device for each queried capture/output buffer.
When testing the GPU h264 encoder on Nvidia's Jetson Nano, this caused an
infinite loop because avbuf->buf.length included some empty buffers (i.e.
where avbuf->buf.m.planes[i].length = 0), meaning that the counter was
never incremented and break was never reached.
This is fixed in the commit by using a well defined iteration range.

kbps to comply with the MP2 standard. Example error:
