Subject: [PATCH] brcmfmac: fix brcmf_vif_clear_mgmt_ies when stopping AP

This removes the following error log when stopping AP:

ieee80211 phy0: brcmf_vif_set_mgmt_ie: vndr ie set error : -52

It happened if
1) previously wlan interface was in station mode (wpa_supplicant) and
   connected to a hotspot
2) then started AP mode (hostapd)
3) and then stopped AP mode.

The error happened when it tried to clear BRCMF_VNDR_IE_PRBREQ_FLAG.
This flag is not set in `brcmf_config_ap_mgmt_ie`, but
BRCMF_VNDR_IE_ASSOCRSP_FLAG is set instead.
