From: Russell King <rmk+ker...@arm.linux.org.uk>
get_pages() tries to convert a page array into a scatterlist. If this
fails, we bail out without freeing the page array. Add a call to
drm_gem_put_pages() to drop the reference gained in drm_gem_get_pages(),
indicating that we didn't access the pages.
