scsi: ibmvfc: add wrapper to get vhost associated with a channel struct

Browse source

Add ibmvfc_channels_to_vhost() to recover the parent struct ibmvfc_host
from a protocol-specific struct ibmvfc_channels.

Later patches need to operate on either the SCSI or NVMe channel group
and still access host-wide state such as the primary CRQ, device, and
logging context. Centralize that mapping in a helper instead of open-
coding container lookups at each call site.
