s390/3270: fix missing device_destroy() call 

Unloading the fs3270 kernel module does not remove the created
"3270/tub" device.  Reloading the module then causes a sysfs warning:
"sysfs: cannot create duplicate filename '/devices/virtual/3270/3270!tub'".

Call device_destroy() in the module exit function to solve this issue.
