[PATCH v2 1/3] ibmvscsi: Wire up host_reset() in the drivers scsi_host_template

[Tyrel Datwyler]

From: Tyrel Datwyler <tyr...@linux.vnet.ibm.com>

Wire up the host_reset function in our driver_template to allow a user
requested adpater reset via the host_reset sysfs attribute.

Example:

echo "adapter" > /sys/class/scsi_host/host0/host_reset
