cifs: use new enum for ses_status
ses->status today shares statusEnum with server->tcpStatus. This has been confusing, and tcon->status has deviated to use a new enum. Follow suit and use new enum for ses_status as well. Signed-off-by: Shyam Prasad N <[email protected]> Signed-off-by: Steve French <[email protected]>
