002660c4f0 nvme: add transport get_max_sges abstraction
For pcie, this just equals the number of SGLs we can fit
into the per-tracker memory.

For rdma, this is just set to 1 for now since nvme_rdma.c
does not support multiple SGEs yet.  Once that support is
added, this will change to use MSDBD (Maximum SGL Data Block
Descriptors) instead from the controller identify data.

ce4fcbce71 nvme: add I/O qpair creation options
Add a new struct spdk_nvme_io_qpair_opts to allow the user to override
controller options on a per-I/O qpair basis.

Existing callers with qprio == 0 can be updated to:

  ... = spdk_nvme_ctrlr_alloc_io_qpair(ctrlr, NULL, 0);

Callers that need to specify a non-default qprio should be updated to:

  struct spdk_nvme_io_qpair_opts opts;
  spdk_nvme_ctrlr_get_default_io_qpair_opts(ctrlr, &opts, sizeof(opts));
  opts.qprio = SPDK_NVME_QPRIO_...;
  ... = spdk_nvme_ctrlr_alloc_io_qpair(ctrlr, &opts, sizeof(opts));

13f8cf1536 nvme: add NVME_QUIRK_DELAY_AFTER_QUEUE_ALLOC
The VirtualBox emulated NVMe device will intermittently
hang on the first read/write command after an I/O
qpair has been allocated.  The frequency of the hang
diminishes if a delay is added after allocating the I/O
qpair - until it disappears completely with a 100us delay.
So add a quirk to insert this delay.

Note - the 100us delay was tested by running
the hello_world example app 50000 times.

320c7fb825 nvme: drop Set Features of Keep Alive Timeout
The NVMe over Fabrics transports should already be setting this in the
initial admin queue Connect command, so setting it again is not useful.

The kernel NVMe over Fabrics target additionally has a bug in the Set
Features - Keep Alive Timeout handler (it is extracting the KATO value
from the wrong offset in the command), so this works around the kernel
bug by not sending the Set Features command at all.
