Gerald Schaefer ccaf655396 [S390] monreader: fix use after free bug with suspend/resume ...

The monreader device driver doesn't set dev->driver_data to NULL after
freeing the corresponding data structure. This leads to a use after
free bug in the freeze/thaw suspend/resume functions after the device
has been opened and closed once. Fix this by clearing dev->driver_data
in the close() function.
