[SCSI] scsi_error: add target reset handler
The problem is that serveral drivers are sending a target reset from the device reset handler, and if we have multiple devices a target reset gets sent for each device when only one would be sufficient. And if we do a target reset it affects all the commands on the target so the device reset handler code only cleaning up one devices's commands makes programming the driver a little more difficult than it should be. This patch adds a target reset handler, which drivers can use to send a target reset. If successful it cleans up the commands for a devices accessed through that starget.
