NVMe: Add compat_ioctl
Make ioctls work for 32-bit applications on 64-bit kernels. The structures are defined to be the same for both 32- and 64-bit applications, so we can use the same handler for both. Reported-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Matthew Wilcox <matthew.r.wilcox@intel.com>
