From: Jérôme Pouiller <jerome.pouil...@silabs.com>
When ERP changes, mac80211 call wfx_bss_info_changed() with
BSS_CHANGED_ERP_* and with BSS_CHANGED_BEACON.
The driver already update beacon template because of
BSS_CHANGED_BEACON. It is not necessary to also update beacon template
because of BSS_CHANGED_ERP_*.
