[SCSI] don't call ips_eh_reset in ips_queue to avoid deadlock

When the locking was changed in the eh code ips_eh_reset was changed
so that it was a wraper around __ips_eh_reset and all ips_eh_reset
does is grab the host lock and then calls __ips_eh_reset.

In the queuecommand, ips_queue is called with the host_lock held so if
it calls ips_eh_reset we will have a problem. This patch just has
ips_queue call __ips_eh_reset.

Patch is only compile tested. I do not have the HW.
