James Bottomley a8733c7baf [SCSI] fix medium error problems with some arrays which can cause data corruption 
Our current handling of medium error assumes that data is returned up
to the bad sector.  This assumption holds good for all disk devices,
all DIF arrays and most ordinary arrays.  However, an LSI array engine
was recently discovered which reports a medium error without returning
any data.  This means that when we report good data up to the medium
error, we've reported junk originally in the buffer as good.  Worse,
if the read consists of requested data plus a readahead, and the error
occurs in readahead, we'll just strip off the readahead and report
junk up to userspace as good data with no error.

The fix for this is to have the error position computation take into
account the amount of data returned by the driver using the scsi
residual data.  Unfortunately, not every driver fills in this data,
but for those who don't, it's set to zero, which means we'll think a
full set of data was transferred and the behaviour will be identical
to the prior behaviour of the code (believe the buffer up to the error
sector).  All modern drivers seem to set the residual, so that should
fix up the LSI failure/corruption case.
