Noralf Trønnes cf19fa2cfa drm/client: Fix double free in error path ...

This fixes a static checker warning:

	drivers/gpu/drm/drm_client.c:289 drm_client_buffer_create()
	error: double free of 'buffer'

Extend drm_client_buffer_delete() to handle the case when there's no
dumb buffer attached and drop the extra kfree.

Fixes: c76f0f7cb5 ("drm: Begin an API for in-kernel clients")
