PATCH v4 7/7 nvme-fabrics: Add FC LLDD loopback driver to test FC-NVME

Add FC LLDD loopback driver to test FC host and target transport within nvme-fabrics

To aid in the development and testing of the lower-level api of the FC transport, this loopback driver has been created to act as if it were a FC hba driver supporting both the host interfaces as well as the target interfaces with the nvme FC transport.
