s390/dasd: remove dasd_fba_probe() wrapper

commit e03c5941 ("s390/dasd: Remove unused parameter from
dasd_generic_probe()") allows us to wire the generic callback up
directly, avoiding the additional level of indirection.

While at it also remove the forward declaration for the dasd_fba_driver
struct, it's no longer needed.
