r13481: As far as I can tell, my changes in -r 12863 were dangerously untested.
We do need the gsskrb5_get_initiator_subkey() routine. But we should
ensure that we do always get a valid key, to prevent any segfaults.
Without this code, we get a different session key compared with
Win2k3, and so kerberised smb signing fails.
