quota: Check for register_shrinker() failure.
commit 88bc0ede8d35edc969350852894dc864a2dc1859 upstream.
register_shrinker() might return -ENOMEM error since Linux 3.12.
Call panic() as with other failure checks in this function if
register_shrinker() failed.
Fixes: 1d3d4437eae1 ("vmscan: per-node deferred work")
