connected to the same Subsystem, for IO queues' creation process, it
will use cntlid field with 0 for current code logic.

The NVMe over Fabrics target was storing the PCI device pointer for each

is exposed via the get_nvmf_subsystems RPC.
Also update the same code path to use the new spdk_pci_device_get_addr()
function for brevity.

- Split the part that gets a PCI device's address into its own function,
spdk_pci_device_get_addr(). This is useful outside of the comparison
function and is orthogonal to comparing addresses.
- Make the comparison function take two addresses instead of a device
and an address. The more general form will be useful with addresses
that are not directly associated with a device. Because of this, also
rename the function from spdk_pci_device_compare_addr() to
spdk_pci_addr_compare().
- Return a signed value similar to strcmp() so that addresses can be
ordered, not just compared for equality.

For iWARP devices, buffers that are intended to be the
target of an RDMA read initiated by the target must additionally
have IBV_ACCESS_REMOTE_WRITE permission. This is because iWARP's
RDMA read path essentially requests the remote side to do
an RDMA write.
This is unfortunate because there is no way to differentiate between
memory that the remote side can do an RDMA write to and memory
that will only be the target of RDMA reads initiated by the
target. There is nothing we can do about this serious deficiency in
the specification, however, so we have to live with it.
