The API `spdk_nvme_map_prps` is used in nvmf/vfio-user to remap VM's NVMe command data buffer to local virtual address, and for command using PRP, there maybe multiple pages, when parsing the PRP list to local IOVs, we need a parameter to check that the maximum number of vectors can't exceed the IOVs, this API can't meet the requirement, while here, we add a new API `spdk_nvme_map_cmd` and with a new parameter `max_iovcnt` to fix this case, and it can also cover the command using SGL in the coming patches.
