Two callbacks, .dumb_destroy and .gem_prime_import, were initialized to their default implementations, so they are just kept empty now.

Remove the callbacks as they are now unused. The only exception is .gem_prime_mmap, which is still in use by several drivers. What is also gone is gem_vm_ops in struct drm_driver. All drivers now use struct drm_gem_object_funcs.vm_ops instead. While at it, the patch also improves error handling around calls to .free and .get_sg_table callbacks.
