When using DPDK PCI support via VFIO, the PCI device is reset
immediately before calling the PCI driver's init function. In some
cases, the device seems to not be ready to handle MMIO accesses right
away. Until the cause of this issue is fully understood, add a 500 ms
sleep as a workaround.

The NVMe specification recommends that orderly shutdown should just
write CC.SHN while the controller is still enabled rather than writing
CC.EN = 0 first.
This also allows removal of the now-unused nvme_ctrlr_disable() and
nvme_ctrlr_wait_for_ready() functions.

This patch is used to handle the memory leak issue when
a parent nvme_request is free. In our current code,
we did not free the nvme_request allocated by the children
in the exceptional case.

If only one descriptor is needed, there is a special case in the spec for
SGL1 using the Data Block descriptor type. Add a comment to make it
clear what is going on.
Also tweak the SGL1 setup to copy from the first SGL descriptor list
element instead of relying on the last value from the loop above, since
that could be easily broken by accident.

_nvme_qpair_build_hw_sgl_request() will only be called for payload_size

was handling nseg == 0, and add an assert to document the payload_size
requirement.

It also allows removing the lib/nvme directory from the Doxyfile, so

IDs.
