NACK.  This will break ABI compatibility, which is way important than
getting the ioctl encoding incorrect.

If you really care, I suppose we could add an EXT4_IOC_GETSTATE_OLD
for the old value, and then support EXT4_IOC_GETSTATE and
EXT4_IOC_GETSTATE_OLD for a decade or two until all of the binaries in
the world get recompiled.

Is it worth it?  Eh....
