[PATCH 4/5] reminder comment about register_ioctl32_conversion

[Michael S. Tsirkin]

This is just a split off from Andi's patch, so I didnt add my SOB here.

Signed-off-by: Andi Kleen <ak@xxxxxx>

Since its too early to deprecate (un)register_ioctl32_conversion,
add a comment for that time when we do.
