Initialize the fave and cost arrays fully

We try to be smart in sendMTFValues by initializing just nGroups
number of elements instead of all BZ_N_GROUPS elements. But this means
the compiler doesn't know all elements are correctly initialized and
might warn. The arrays are really small, BZ_N_GROUPS, 6 elements. And
nGroups == BZ_N_GROUPS is the common case. So just initialize them all
always. Using a constant loop might also help the compiler to optimize
the initialization.
