Simplify the error handling of nvme_fc_create_hw_io_queues(), this saves us
one variable and one level of indentation.

Dan Carpenters's tool caught a pointer reference - should have been
just ptr, not &ptr.

Don't bother. Remove the pointer value in the printf. Its irrelevant.

Implements the FC-NVME T11 definition of how nvme fabric capsules are
performed on an FC fabric. Utilizes a lower-layer API to FC host adapters
to send/receive FC-4 LS operations and FCP operations that comprise NVME
over FC operation.

The T11 definitions for FC-4 Link Services are implemented which create
NVMeOF connections.  Implements the hooks with blk-mq to then submit admin
and io requests to the different connections.
