For an NVMe read, send the completion immediately
following the RDMA WRITE, without waiting for
the acknowledgement. RDMA is strictly ordered,
so the WRITE will arrive before the completion.

Except for a CONNECT capsule, always use the central data
pool for RDMA READ/WRITE operations. The in-capsule
data buffer is associated with the receive operation
while the pool data buffers are associated with the
completion, and using the in-capsule data buffer
causes a lifetime mismatch.

The RDMA protocol this module uses is strictly ordered,
which means messages are delivered in exactly the order
they are sent. However, we have detected a number of
cases where the acknowledgements for those messages
arrive out of order. This patch attempts to handle
that case.
Separate the data required to post a recv from the
data required to send a response. If a recv arrives
when no response object is available, queue the
recv.

remove the unnecessary rte_eal_pci_probe_one() in function
spdk_pci_device_detach(), this could cause error message when we
terminate the application, it will also not make sense try to probe one
device after we detach it, we could call spdk_pci_nvme_device_attach()
instead of spdk_pci_nvme_enumerate() when we have one given device address,
dpdk will try to scan the device and add it back to pci device list then.

The send completions must be processed prior to the
recv completions. However, if the completion queues
are separate this leaves a small window where
a send+recv completion arrive between polling
the send_cq and the recv_cq, resulting in the code
seeing the recv completion prior to the send
completion.
By combining the completion queues, this eliminates
any potential gap. The send completion will always
be processed before the recv completion.
