In order to truly support multi-sgl inline requests in the RDMA
transport, we would need to increase the size of the
spdk_nvme_rdma_req object dramatically. This is because we would need
enough ibv_sge objects in it to support up to the maximum number of SGEs
supported by the target (for SPDK that is up to 16). Instead of doing
that or creating a new pool of shared ibv_sge objects to support that
case, just send split multi-sgl requests through the regular sgl path.

to track the controllers during initialization, and internal

until the list is empty. We introduce a probe context
and move the global list into the context, with the context
we can enable asynchronous probe API in the next patch, also
this can enable parallel probe feature.

Rather than storing nvme_payload::type explicitly, use the SGL reset
function pointer as an indicator: if reset_sgl_fn is non-NULL, then the
payload is an SGL type; otherwise it is a contiguous buffer type.
This eliminates the one-byte type member from struct nvme_payload,
making it an even 32 bytes instead of 33, allowing the removal of the
awkward packing inside struct nvme_request.
