[patch] cifs: fix error code in cifs_match_super()

It looks like there is a typo here where return "rc" which is "success"
instead of PTR_ERR(tlink) which is a negative error code.

I have also removed the unneeded initialization so that GCC has a chance
to warn about this sort of thing next time.

This is a static checker warning and I'm not certain this is the correct
fix.  Please review this one carefully.
