ovl: perform vfs_getxattr() with mounter creds
[ Upstream commit 554677b97257b0b69378bd74e521edb7e94769ff ]
The vfs_getxattr() in ovl_xattr_set() is used to check whether an xattr
exist on a lower layer file that is to be removed. If the xattr does not
exist, then no need to copy up the file.
This call of vfs_getxattr() wasn't wrapped in credential override, and this
is probably okay. But for consitency wrap this instance as well.
