cifs: prevent data race in cifs_reconnect_tcon()
Make sure to get an up-to-date TCP_Server_Info::nr_targets value prior to waiting the server to be reconnected in cifs_reconnect_tcon(). It is set in cifs_tcp_ses_needs_reconnect() and protected by TCP_Server_Info::srv_lock. Create a new cifs_wait_for_server_reconnect() helper that can be used by both SMB2+ and CIFS reconnect code.
