Subject: [PATCH] Use nvme_ioctl.h for newer kernel versions #55

The header linux/nvme.h was replaced by linux/nvme_ioctl.h in kernel versions greater than 4.4: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9d99a8dda154

The needed structs and opcodes are copied into a new header file from nvme.h.
