[PATCH 13/19] staging: wfx: avoid duplicate updating of beacon template

[Jerome Pouiller]

From: Jérôme Pouiller <jerome.pouiller at 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_*.
