floppy: ignore kernel-only members in FDRAWCMD ioctl input
commit ef87dbe7614341c2e7bfe8d32fcb7028cc97442c upstream.
Always clear out these floppy_raw_cmd struct members after copying the
entire structure from userspace so that the in-kernel version is always
valid and never left in an interdeterminate state.
