From: Jeff Layton <jlayton@redhat.com>

commit 1097680d759918ce4a8705381c0ab2ed7bd60cf1 upstream.

sparse says:

fs/ceph/dir.c:1248:50: warning: incorrect type in assignment (different base types)
fs/ceph/dir.c:1248:50: expected restricted __le32 [usertype] mask
fs/ceph/dir.c:1248:50: got int [signed] [assigned] mask

Fixes: 200fd27c8fa2 ("ceph: use lookup request to revalidate dentry")
