Make nouveau_fence_chan refcounted, to make trace_fence_destroy
always return the correct name without a race condition.

This fixes a regression introduced by "drm/nouveau: rework to new fence interface"
(commit 29ba89b237).
The fence sequence should not be reset after creation, the old value is used instead.
On destruction the final value is written, to prevent another source of accidental
wraparound in case of a channel being destroyed after a hang, and unblocking any other
channel that may wait on the about-to-be-deleted channel to signal.
I'm nothing if not optimistic about any hope of recovery from that. ;-)

Really, the legacy buffer api should be dead, especially for all these
newfangled drivers. I suspect this is copypasta from the transitioning
days, which probably originated in radeon.

Pull drm fixes from Dave Airlie:
"A bunch of radeon fixes for oops on module unload, and problems with
resetting the dma engine, one nouveau fix for black boxes in rendering
on my mbp retina, one sti fix, and a couple of intel fixes"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/nouveau: ltc/gf100-: fix cbc issues on certain boards
drm/bochs: add missing drm_connector_register call
drm/cirrus: add missing drm_connector_register call
drm/radeon: Fix typo 'addr' -> 'entry' in rs400_gart_set_page
drm/nouveau/runpm: fix module unload
drm/radeon/px: fix module unload
vgaswitcheroo: add vga_switcheroo_fini_domain_pm_ops
drm/radeon: don't reset dma on r6xx-evergreen init
drm/radeon: don't reset sdma on CIK init
drm/radeon: don't reset dma on NI/SI init
drm/radeon/dpm: fix resume on mullins
drm/radeon: Disable HDP flush before every CS again for < r600
drm/radeon: delete unused PTE_* defines
drm/i915: Add limited color range readout for HDMI/DP ports on g4x/vlv/chv
drm: sti: do not iterate over the info frame array
drm/i915: Fix SRC_COPY width on 830/845g
A mismatch between FB and LTC's idea of how big a large page is causes
issues such as black "holes" in rendering to occur on some boards
(those where LTC is configured for 64KiB large pages) when compression
is used.
Confirmed to fix at least the GK107 MBP.

nv92 hardware has only 16 interrupt lines, while nv94 and later
has 32. Accessing 0xe0c{0,4} registers on nv92 can lead to incorrect
PDISP setup. This is a regression introduced with
