[PATCH 01/18] libsas: cleanup spurious calls to scsi_schedule_eh

[Dan Williams <dan.j.williams@intel.com>]

From: Maciej Trela <maciej.trela@intel.com>

eh is woken up automatically by the presence of failed commands,
scsi_schedule_eh is reserved for cases where there are no failed
commands.  This guarantees that host_eh_sceduled is only incremented
when an explicit eh request is made.
