[SCSI] fix ABORTED_COMMAND looping forever problem

Instead of terminating after five retries, commands terminated by
ABORTED_COMMAND sense are retrying forever.  The problem was
introduced by:

commit b60af5b0adf0da24c673598c8d3fb4d4189a15ce

    [SCSI] simplify scsi_io_completion()

Which introduced an error whereby ABORTED_COMMAND now gets erroneously
retried in scsi_io_completion.  Fix this by returning the behaviour
back to the default no retry.
