From: Namjae Jeon <linkinjeon@xxxxxxxxxx>

[ Upstream commit f5c779b7ddbda30866cf2a27c63e34158f858c73 ]

This racy issue is triggered by sending concurrent session setup and
logoff requests. This patch does not set connection status as
KSMBD_SESS_GOOD if state is KSMBD_SESS_NEED_RECONNECT in session setup.
And relookup session to validate if session is deleted in logoff.
