drm/savage: dereferencing an error pointer
commit f7741aa75e76440f4e9ecfe512feebe9bce33ca8 upstream.
A recent cleanup changed the kmalloc() + copy_from_user() to
memdup_user() but the error handling wasn't updated so we might call
kfree(-EFAULT) and crash.
Fixes: a6e3918bcdb1 ('GPU-DRM-Savage: Use memdup_user() rather than duplicating')
