[CIFS] Fix cifsd so shuts down when signing fails during mount
Fixes two problems:
1) we dropped down to negotiating lanman if we did not recognize the
mechanism (krb5 e.g.)
2) we did not stop cifsd (thus will fail when doing rmod cifs with
slab free errors) when we fail tcon but have a bad session (which is
the case in which signing is required but we don't allow signing on
the client)
It also turns on extended security flag in the header when passing
"sec=krb5" on mount command (although kerberos support is not done of
course)
