drm/msm: Acquire reservation lock in GEM pin/unpin callback
Export msm_gem_pin_pages_locked() and 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
msm accordingly by pushing locking out of the implementation. A
follow-up patch will fix locking for all GEM code at once.
