nbd: ignore non-nbd ioctl's
In testing we noticed that nbd would spew if you ran a fio job against the raw device itself. This is because fio calls a block device specific ioctl, however the block layer will first pass this back to the driver ioctl handler in case the driver wants to do something special. Since the device was setup using netlink this caused us to spew every time fio called this ioctl. Since we don't have special handling, just error out for any non-nbd specific ioctl's that come in. This fixes the spew. Signed-off-by:Josef Bacik <jbacik@fb.com> Signed-off-by:
