These page pointers shouldn't be visible to TTM in the first place, but
until we fix that up, don't clear the page metadata because that
will upset the exporter.

Commit drm/ttm: ttm object security fixes for render nodes introduced a
regression where, if a TTM object was opened multiple times from the same
open file, the caller would spin uninterruptibly in the kernel.

Fix this.

Also avoids printing the errors bitfield if that information has already
been shown.

Also make nv_lockvgac work for nv50+ devices. This should fix
IO_CONDITION and related VBIOS opcodes that read/write the crtc regs.

Not holding the mutex potentially causes corruption of the kernel
channel when page flipping.

Seen on Titan.  NFI what the condition to switch this on is yet, and,
hardcoding it to on currently causes master to report unknown intr

Still essentially a struct of magic values with magic names and unknown
purposes.  But, we will shortly need to be able to mix and match bits of
the previous and next configurations to do a transition reclock, as such,
we can no longer directly use the vbios data with any ease.

This is probably nicer anyway in the long run, for a few reasons.
