AP: Fix checking if DFS is required

Browse source 
Sometimes function hostapd_is_dfs_required() returns -1 which indicates
that it was not possible to check if DFS was required. This happens for
channels from the 2.4 GHz band where DFS checking should not happen.
This can be fixed by returning DFS-not-required for mode different from
IEEE80211A and when DFS support is not available (ieee80211h not set).
