crypto: mv_cesa - fixup error handling in mv_probe()

Browse source 
The error handling in mv_probe() was a bit messed up.  There were some 
gotos to the wrong labels so it ended up releasing stuff that that hadn't
been aquired and not releasing stuff that was meant to be released.  I
shuffled it around a bit to fix it and make it clearer.
