nouveau: bring back legacy mmap handler

nouveau userspace back at 1.0.1 used to call the X server
DRIOpenDRMMaster interface even for DRI2 (doh!), this attempts
to map the sarea and fails if it can't.

Since dfefe4b7d72a8f5702605ab3188bc4d014632f62 from Daniel,
this fails, but only ancient drivers would see it.

Revert the nouveau bits of that fix.
