drm/xe/mmio_gem: Revoke drm_vma_node on xe_mmio_gem destroy
xe_mmio_gem_create() calls drm_vma_node_allow() but nothing ever calls
drm_vma_node_revoke(). The drm_vma_offset_file rb-tree entry allocated
by drm_vma_node_allow() is not freed by drm_gem_object_release(), so
it is leaked on every create/destroy cycle.
Add a struct drm_file * parameter to xe_mmio_gem_destroy() and call
drm_vma_node_revoke() from there, mirroring the drm_vma_node_allow()
call in xe_mmio_gem_create().
Fixes: 1ffcf8b8ae8a ("drm/xe: Support for mmap-ing mmio regions")
