[ Upstream commit 7ccc1465465d78e6411b7bd730d06e7435802b5c ]
Call cifs_reconnect() to wake up processes waiting on negotiate protocol to handle the case where server abruptly shut down and had no chance to properly close the socket.
Simple reproducer:
ssh 192.168.2.100 pkill -STOP smbd mount.cifs //192.168.2.100/test /mnt -o ... [never returns]
