Revert "[SCSI] extend the last_sector_bug flag to cover more sectors"

This reverts commit 5e9a37cc24ec5f00228c5523aa438f29d6aa9ac0, since it
seems to break some other USB storage devices (at least a JMicron USB to
ATA bridge).  As such, while it apparently fixes some cardreaders, it
would need to be made conditional on the exact reader it fixes in order
to avoid causing regressions.
