The NVMe submission queue head wraparound point can be determined in the
generic NVMe over Fabrics layer; it should not be using the RDMA
connection queue depth.

Property Set of CC.SHN is not supposed to terminate the session - remove
the commented-out code that was attempting to do this.

These NVMf spec structure definitions are the same as the equivalent

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.

The whole cleanup process is now started by
spdk_shutdown_nvmf_subsystems(). Each subsystem will clean up its
session, if any, and each session will clean up its connections.

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
optional to allow read-only fields).
Remove handling for fields declared as "reserved" in the NVMe over
Fabrics 1.0 specification.
Also simplify the vcprop structure to only contain the required fields.

These are not supported (and did not actually function) in NVMe over
