manpage: adjust description of libva deinterlacer ref direction mess

Eventually I'll just remove this option. But it's probably good to leave
it for while, possibly for letting Mesa VA driver users test and confirm
this.

:yes: Only deinterlace frames marked as interlaced (default).
``reversal-bug=<yes|no>``
:no: Use the API as it appears to be documented. Reported to work well
with Mesa drivers.
:yes: Switch surface forward and backwards references (default). Appears
to work (or work better than ``no``) with Intel drivers. Matters
only for the advanced deinterlacing algorithms.
:no: Use the API as it was interpreted by older Mesa drivers. While
this interpretation was more obvious and inuitive, it was
apparently wrong, and not shared by Intel driver developers.
:yes: Use Intel interpretation of surface forward and backwards
references (default). This is what Intel drivers and newer Mesa
drivers expect. Matters only for the advanced deinterlacing
algorithms.
