Subject: [PATCH] ksun_m6: Fix initialization of new memories

Explicitly set a few extra bits to zero to initialize correctly new
memory slots.

_unk3/_unk4 seem to be part of compander/hopping respectively, even
though only a single value for both is accepted.

Setting _unk3 to 1 (compander:0b10) makes the radio ignore the channel
completely. The original software also refuses to decode the slot and
fail with a generic error.

Setting _unk4 to 1 (hopping:0b10) works on the radio, but still causes
the original software to fail with an error.
