imc: use correct position for flcoeffs2 calculation
flcoeffs2[pos] should be the log2 of flcoeffs1[pos].
flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf,
causing problems further down.
This seems to have been copied from imc_decode_level_coefficients in
commit 4eb4bb3 without updating the position.
