Amir Goldstein c7aee3941e ovl: take mnt_want_write() for removing impure xattr
commit a5a927a7c82e28ea76599dee4019c41e372c911f upstream.

The optimization in ovl_cache_get_impure() that tries to remove an
unneeded "impure" xattr needs to take mnt_want_write() on upper fs.

Fixes: 4edb83bb1041 ("ovl: constant d_ino for non-merge dirs")
