drm/gem: Take reservation lock for vmap/vunmap operations
The new common dma-buf locking convention will require buffer importers to hold the reservation lock around mapping operations. Make DRM GEM core to take the lock around the vmapping operations and update DRM drivers to use the locked functions for the case where DRM core now holds the lock. This patch prepares DRM core and drivers to the common dynamic dma-buf locking convention.
