drm: make drm_file use keyed wakeups
Some processes, such as systemd, are only polling for EPOLLERR|EPOLLHUP.
As drm_file uses unkeyed wakeups, such a poll receives many spurious
wakeups from uninteresting events.
Use keyed wakeups to allow the wakeup target to more efficiently discard
these uninteresting events.
