[SCSI] fusion: fix domain validation loops

After host reset, the device are programmed to default asyn narrow nego.
We need to reprogram the parameter back to previous values.  If the host
reset is called as a result of spi_dv_device() commands timing out, its
possible to get into an infinite loop of dv to host reset.  This will
prevent that case, as we merely program old values.  If host reset is
called outside context of domain validation, then we can  call
spi_dv_device.
