The block (LBA) specified must not exceed the last addressable LBA, which is dev->nr_sectors - 1. So fix the correct check is "if (block >= dev->n_sectors)" and not "if (block > dev->n_sectords)".

Additionally, the asc/ascq to return for an LBA that is not a zone start LBA should be ILLEGAL REQUEST, regardless if the bad LBA is out of range.

If the ALL bit is set in the ZBC_OUT command, the command zone ID field (block) should be ignored.
