esp_scsi: fix reset cleanup spinlock recursion
patch 522939d45c293388e6a360210905f9230298df16 in mainline.
The esp_reset_cleanup() function is called with the host lock held and
invokes starget_for_each_device() which wants to take it too. Here is a
fix along the lines of shost_for_each_device()/__shost_for_each_device()
adding a __starget_for_each_device() counterpart which assumes the lock
has already been taken.
Eventually, I think the driver should get modified so that more work is
done as a softirq rather than in the interrupt context, but for now it
fixes a bug that causes the spinlock debugger to fire.
While at it, it fixes a small number of cosmetic problems with
starget_for_each_device() too.
