nvidiafb: prevent triggering of softlockup
If the chip locks up, we get into a long polling loop,
where the softlockup detector kicks in.
See https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=151878
for an example.
[adaplas]
Chip lockup can occur at 3 points (flush, sync, and wait). Consolidate and
allow the driver to go to safe mode cleanly.
