These can be simplified and merged into the subsystem.
Remove the concept of mappings from subsystems and replace
it with a list of hosts and ports. The host is optional -
not specifying a host means any host can connect.

Set a status code in the response capsule for each possible error case.
Also enforce CC.EN == 1 before I/O connect.
The NVMf spec requires that the controller is enabled before any I/O
queue Connect commands are allowed.

spdk_shutdown_nvmf_subsystems(). Each subsystem will clean up its
session, if any, and each session will clean up its connections.

There is only one controller per subsystem, so therefore
there can be 0 or 1 sessions. Change the list of sessions
to a pointer that can be NULL if no session exists.

This was intended to track the number of NVMe device
queues per session, but there is only one hardware
queue per session. It was conflated with the number
of RDMA queues in several places as well.

Create a list of valid properties with get and set callbacks (set is

Remove handling for fields declared as "reserved" in the NVMe over
Fabrics 1.0 specification.

Multiple NVMe controllers within a subsystem does not work correctly,
since we would need to virtualize the controller data, namespace IDs,
and so on. For now, only allow pass-through mapping of a single NVMe
controller per subsystem.

Previously, we used cap_lo and cap_hi to represent the 32-bit halves of
the full CAP register. However, it is simpler to keep them in a single
64-bit structure, and is no less efficient on 64-bit platforms.
Also name the NSSRS field from NVMe 1.2, which was previously reserved.
