Aaro Koskinen 49799fee82 [SCSI] sym53c8xx: Keep transfer negotiations valid
(The patch updated based on testing and comments from Tony Battersby.)

Change the sym53c8xx_2 driver negotiation logic so that the driver will
tolerate better device removals. Negotiation message(s) will be sent
with every INQUIRY and REQUEST SENSE command, and whenever there is a
change in goals or when the device reports check condition.

The patch was made specifically to address the case where you hotswap
the disk using remove-single-device/add-single-device commands through
/proc/scsi/scsi. Without the patch the driver keeps using old transfer
parameters even though the target is reset and reports check condition,
so the data transfer of the very first INQUIRY will fail.
