[ Upstream commit 99f280700b4cc02d5f141b8d15f8e9fad0418f65 ]

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.
