ASoC: dapm: Fix dapm_set_path_status() connect 

dapm_set_path_status() sets connect incorrectly in the case max > 1 with invert.
In that case, the raw disconnect value should be max, which corresponds to the
userspace value 0.

This use case currently does not appear upstream, but it could break
SOC_DAPM_SINGLE() or SOC_DAPM_SINGLE_TLV() elsewhere or in the future.

This patch completes commit 3a9abe8.
