s390/dasd: Fix potential NULL pointer dereference
dasd_release_space() checks the implementation of the is_ese()
discipline function before calling it to determine if a given device is
an ESE DASD.
The current usage of the logical AND operator will lead to a NULL
pointer dereference as the function is called even if the function
pointer is NULL.
Fix this by using the logical OR operator.
