            drm_wait_netbsd.h

Log Message:
Fix result of DRM_TIMED_WAIT_UNTIL.

This has to return a positive number of ticks left if we haven't
timed out in order to match the semantics of Linux waitqueues.

This also fixes the amount of time for timeout if we ever wait for
more than one iteration.

Now we can actually wait for results from the ring buffers!
