drm/qxl: Acquire reservation lock in GEM pin/unpin callbacks
Acquire the reservation lock directly in GEM pin callback. Same for
unpin. Prepares for further changes.
Dma-buf locking semantics require callers to hold the buffer's
reservation lock when invoking the pin and unpin callbacks. Prepare
qxl accordingly by pushing locking out of the implementation. A
follow-up patch will fix locking for all GEM code at once.
