scsi: lpfc: vmid: Add datastructure for supporting VMID in lpfc
Add the primary datastructures needed to implement VMID in the lpfc
driver. Maintain the capability, current state, and hash table for the
vmid/appid along with other information. This implementation supports the
two versions of vmid implementation (app header and priority tagging).
