According to bspec, result_lines > 31 is only a maximum for latency
level 1 through 7, so correctly apply the check there.
This is required to make NV12 work.

The register still has only 5 bits for the line watermark. However the
spec says "Hardware ignores the lines for the level 0 watermark.", so
I think what we should be doing is just setting the line watermark to
zero for level 0.

According to bspec, result_lines > 31 is only a maximum for latency
level 1 through 7.
For level 0 the number of lines is ignored, so always write 0 there
to prevent overflowing the 5 bits value.
This is required to make NV12 work.

Looks like we could just skip computing res_lines entirely.
But this should work too so
