nfsd: fix possible oops on re-insertion of rpcsec_gss modules

The handling of the re-registration case is wrong here; the "test" that was
returned from auth_domain_lookup will not be used again, so that reference
should be put.  And auth_domain_lookup never did anything with "new" in
this case, so we should just clean it up ourself.

Thanks to Akinobu Mita for bug report, analysis, and testing.
