[PATCH 5/6] lpfc: revise nvme max queues to be hdwq count

Driver is setting the initiator nvme template with a max hw
queues value of the present cpu count which is odd. It should
be registering the number of hdwq queues (queues created on the adapter).

Change to set nvme tempate, in all cases, to the number of hardware
queues.
