ANDROID: xattr: Pass EOPNOTSUPP to permission2

Browse source 
The permission call for xattr operations happens regardless of
whether or not the xattr functions are implemented.

The xattr functions currently don't have support for permission2.
Passing EOPNOTSUPP as the mount point in xattr_permission allows
us to return EOPNOTSUPP early in permission2, if the filesystem
supports it.
