scsi: ibmvfc: add helper to check NVMe/FC support with active channels

Browse Source 
It can be the case that NVMeoF is enabled on both the client and VIOS,
but no queues are configured making the need to do NVMe target discovery
pointless. Add a helper to short hand the capabilities check and active
NVMe queue check.
