Luis Henriques 71f2cc64d0 ceph: quota: fix null pointer dereference in quota check 
This patch fixes a possible null pointer dereference in
check_quota_exceeded, detected by the static checker smatch, with the
following warning:

   fs/ceph/quota.c:240 check_quota_exceeded()
    error: we previously assumed 'realm' could be null (see line 188)

Fixes: b7a2921765cf ("ceph: quota: support for ceph.quota.max_files")
