cifs: Process post session setup code in respective dialect functions.
Move the post (successful) session setup code to respective dialect routines.
For smb1, session key is per smb connection.
For smb2/smb3, session key is per smb session.
If client and server do not require signing, free session key for smb1/2/3.
If client and server require signing
smb1 - Copy (kmemdup) session key for the first session to connection.
Free session key of that and subsequent sessions on this connection.
smb2 - For every session, keep the session key and free it when the
session is being shutdown.
smb3 - For every session, generate the smb3 signing key using the session key
and then free the session key.
There are two unrelated line formatting changes as well.
