[SCSI] scsi_error: fix target reset handling
There's a target reset bug.
This loop:
for (id = 0; id <= shost->max_id; id++) {
Never terminates if shost->max_id is set to ~0, like aic94xx does.
It's also pretty inefficient since you mostly have compact target
numbers, but the max_id can be very high. The best way would be to
sort the recovery list by target id and skip them if they're equal,
but even a worst case O(N^2) traversal is probably OK here, so fix it
by finding the next highest target number (assuming n+1) and
terminating when there isn't one.
