scsi: target: tcm_loop: Remove redundant driver match function

If there is no driver match function, the driver core assumes that each
candidate pair (driver, device) matches. See driver_match_device().

pseudo_lld_bus_match() always returns 1 and is therefore equivalent to not
registering a match function. Remove it.
