Not in a very nice way, though.  The real problem here is that we

 a) can still return a failure after sb->s_root is set
 b) abuse hfsplus_put_super for error handling, which is totally
    ill-suited.

Take a look at the patch in
https://bugzilla.kernel.org/show_bug.cgi?id=27932 for a proper fix.
