qcacld-3.0: Skip channel validation in case of acs

qcacld-2.0 to qcacld-3.0 propagation

As per current implementaion whenever ACS is enabled via
INI all the update beacon from cfg80211 module fails because
sapconfig channel points to AUTO_CHANNEL_SELECT(0).

When driver ACS is enabled skip channel validation to fix
this issue.
