EDAC, mv64x60: Fix an error handling path

[ Upstream commit 68fa24f9121c04ef146b5158f538c8b32f285be5 ]

We should not call edac_mc_del_mc() if a corresponding call to
edac_mc_add_mc() has not been performed yet.

So here, we should go to err instead of err2 to branch at the right
place of the error handling path.
