s3-librpc: Remove gse_verify_server_auth_flags

gensec_update() ensures that DCE-style and sign/seal are negotiated correctly
for DCE/RPC pipes.  Also, the smb sealing client/server already check for the
gensec_have_feature().

This additional check just keeps causing trouble, and is 'protecting'
an already secure negoitated exchange.
