[ 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.
