hrd_buffer_size and hrd_initial_buffer_fullness are set in bits, while
driver takes the vbvBuf size in 16 kbits. The mismatch will cause
quality issue.
One way to solve this issue in FFmpeg level is set the bufsize
specially for mpeg2 as the unit of 16 kbits, and discard the default

I believe it is a little different as this patch.
MFX_SCALING_MODE_DEFAULT/ MFX_SCALING_MODE_QUALITY are only buildable with
QSV_HAVE_SCALING_CONFIG.
It is same as the libx264 case we discussed.
