scsi eh (in linux 2.4) retries a command without limit

[Saeed Bishara <Saeed.Bishara@il.marvell.com>]

Hi,
    I've seen a case where timeout occurs, and one of the timedout 
commands it a read to a sector with ecc corrupted.
    when the error handler enters to action, it retries that read which 
alwasy fails on medium error, but unfortunalty the error handler     
retries it again and again without finish.
    I looked  into the scsi error handler code (kernel 2.4.26), and I 
found that the function scsi_send_eh_cmnd retries the command ( if 
scsi_eh_completed_normally return NEEDS_RETRY) without any restriction 
and without increasing and checking the retries counter.
