AP: Don't try to set NULL WEP default key

hostapd_broadcast_wep_set() can be called without a WEP key set.
Don't try to install a default key in that case.

This patch is not critical for the new API. With key_flag we just would
report an (ignored) error and do nothing. With the patch we simply do
nothing.
