free 'supported mechs' through gss_release_oid_set() call

Attached is a small patch that should be applied before the 8.0

It fixes a problem with a recent patch (authored by me), where
gssapi_cleanup was introduced and gssapi resources are freed.

It turns out that the supported_mechs should not be just freed but
instead freed through gss_release_oid_set.

The error is probably irrelevant in the *ix/bsd environments, but
turned out to be an error under Windows if a dynamic lib (gssapi.dll)
from MIT Kerbereros is used.
