qcacld-3.0: Fix 11ax SAP stop issue after radar received

For 11ax SAP, when received radar, sap_is_chan_change_needed for 11BE
return false sometimes, target freq and bw is same as current, after
CSA, vdev restart failed in lim_process_sme_channel_change_request,
vdev becomes hung in SUSPEND-SP-CSA_RESTART. After 1 min, Kernel trigger
disconnect.

To fix it, if SAP isn't 11BE mode, sap_is_chan_change_needed return
true directly as legacy code.
