brcmfmac: Do not handle link downs for ibss.

Sometimes on module reload and reconnect to ibss a deauth from
other station can be received. This is treated as a link down but
for ibss this is wrong. It will close the interface and no data
is possible. Ignore the firmware generated link down events in
ibss mode, as ibss is always teared down by cfg80211.
