s390/dasd: fix double module refcount decrement

Browse source

[ Upstream commit c3116e62dd ]

Once the discipline is associated with the device, deleting the device
takes care of decrementing the module's refcount.  Doing it manually on
this error path causes refcount to artificially decrease on each error
while it should just stay the same.
