Re-introduce "[SCSI] extend the last_sector_bug flag to cover more sectors"
This re-introduces commit 2b142900784c6e38c8d39fa57d5f95ef08e735d8,
which was reverted due to the regression it caused by commit
fca082c9f1e11ec07efa8d2f9f13688521253f36.
That regression was not root-caused by the original commit, it was just
uncovered by it, and the real fix was done by Alan Stern in commit
580da34847488b404218d1d7f53b156f245f5555 ("Fix USB storage hang on
command abort").
We can thus re-introduce the change that was confirmed by Alan Jenkins
to be still required by his odd card reader.
