[MS-SPNG] requires the NTLMSSP RC4 states to be reset after
the SPNEGO exchange with mechListMic verification (new_spnego).
The 'reset_full' parameter is needed to support the broken
behavior that windows only resets the RC4 states but not the
sequence numbers. Which means this functionality is completely
useless... But we want to work against all windows versions...

It's important to check if got the GENSEC_FEATURE_SIGN and if the caller
wanted it.
The caller may only asked for GENSEC_FEATURE_SESSION_KEY which implicitly
negotiates NTLMSSP_NEGOTIATE_SIGN, which might indicate GENSEC_FEATURE_SIGN
to the SPNEGO glue code.
