nvme: add vectored-io support for user-passthrough
Add a new NVME_IOCTL_IO64_CMD_VEC ioctl that works like the existing
NVME_IOCTL_IO64_CMD ioctl except that it takes and array of iovecs
and thus supports vectored I/O.
- cmd.addr is base address of user iovec array
- cmd.vec_cnt is count of iovec array elements
This patch does not include vectored-variant for admin-commands as most
of them are light on buffers and likely to have low invocation frequency.
