[PATCH v2 4/6] CIFS: set signing flag in SMB2+ TreeConnect if needed

[Aurelien Aptel <aaptel-IBi9RG/b67k@public.gmane.org>]

cifs_enable_signing() already sets server->sign according to what the
server requires/offers and what mount options allows/forbids, so use
that.

this is required for IPC tcon that connects to signing-required servers.
