modesetting: Drop dumb_bo::map_count field and dead unmap code.

Browse Source 
The drm kernel API for dumb BOs apparently doesn't include an unmap
ioctl, so we can't do much here.  It looks like this code was copied
from libkms, which was also unfinished.

We may as well delete the dead variable that simply gets incremented
and never read.
