  lavc/qsvenc_jpeg: add async_depth support
  
  Currently qsv (m)jpeg encoding is broken.
  Regression introducing by the commit(id: c1bcd3): fix async support,
  which requires the minimum async_depth to be 1, instead previous zero.
  But the default async_depth of qsv (m)jpeg encoding is still initialized
  (mostly) as zero.
  
  This patch also abviously improves qsv (m)jpeg encoding performance
  due to the default async_depth is changed to 4.

  Can be checked as:
  -hwaccel qsv -c:v h264_qsv -i ../h264-conformance/CANL2_Sony_E.jsv -c:v
  h264_qsv -b:v 2000k -y qsv.mp4
