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.
