Try to avoid these errors by accounting for at least one sg list entry when calculating cmd_size, regardless of whether the low level driver set a zero sg_tablesize. Tested on 030 m68k with the atari_scsi driver - setting sg_tablesize to SG_NONE no longer results in a crash when loading this driver.

Fix sd_zbc_complete() to be quiet only in the case of REQ_OP_ZONE_RESET, excluding REQ_OP_ZONE_RESET_ALL. Since REQ_OP_ZONE_RESET is the only request handled by sd_zbc_complete(), also simplify the code using a simple if statement.
