[Intel-gfx] [PATCH] drm/i915: Free the imported shmemfs file for phys objects

[Chris Wilson]

Matthew spotted that we lost the fput() for phys objects now that we are
not relying on the core to cleanup the GEM object. (For the record, phys
objects import the shmemfs from their original set of pages and keep it
to provide swap space, but we never transform back into a shmem object.)
