cifs: fix session state check in reconnect to avoid use-after-free issue

Browse source

[ Upstream commit 99f280700b ]

Don't collect exiting session in smb2_reconnect_server(), because it
will be released soon.

Note that the exiting session will stay in server->smb_ses_list until
it complete the cifs_free_ipc() and logoff() and then delete itself
from the list.
