This change is already in master, see
https://git.lede-project.org/?p=source.git;a=commitdiff;h=5e481881d7abd814abbf40a046be90cbaf835e72

Let's just backport this trivial change to lede-17.01.

1a16cb9c67f0d2c530914aec31c721b75f03a908 moved setting beacon_int from
wpa_supplicant_add_network() to hostapd_prepare_device_config(). Does
encrypted IBSS/mesh setup somehow not use hostapd_prepare_device_config()?
How do the resulting hostapd.conf look at the moment?
