scsi: scsi-sysfs: Adjust error returned for adapter reset request
If scsi_host_template->host_reset is NULL and the user requests an
adapter reset through
echo adapter > /sys/class/scsi_host/hostx/host_reset
-EINVAL will be returned even though the "adapter" argument is perfectly
valid.
Change this so that we only return -EINVAL if the provided string is
invalid. If the host does not implement a ->host_reset function we'll
return -EOPNOTSUPP.
