CIFS: set signing flag in SMB2+ TreeConnect if needed

aaptel · smfrench · commit b9043cc5b99e · 2017-03-01T22:26:11.000-06:00
cifs_enable_signing() already sets server-&gt;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.
