Most of the time, the data transfer residual is initialized to 0 before the
SCSI command is queued, so it is not necessary to set it to 0 explicitly if
the command completes successfully. However, if the command fails with e.g.
queue full status, the data transfer residual will be set to a nonzero value
when the command is queued for retry. This patch ensures that the residual
is set to 0 if the retry completes successfully rather than retaining the
residual from the first execution of the command.
