hostapd: clear start_disabled when adding a BSS to an enabled iface

Browse Source 
In AP+STA mode, wifi-scripts emits start_disabled=1 in the per-BSS
section of the generated hostapd config so that hostapd defers
beaconing on every BSS until apsta_state up clears the flag for the
whole iface (uc_hostapd_iface_start clears start_disabled on every BSS
and calls ieee802_11_set_beacon).

When a new BSS is added later via iface.add_bss while the iface is
already in HAPD_IFACE_ENABLED state, the freshly parsed config still
carries start_disabled=1 for that BSS. hostapd_setup_bss is invoked
with start_beacon=true, but hostapd_start_beacon then skips
ieee802_11_set_beacon because conf->start_disabled is set. The kernel
netdev is created without ever starting beacons, the carrier never
comes up, and probe-response transmission attempts fail with
"handle_probe_req: send failed".

Mirror what iface.start does: when the iface is already enabled, the
apsta channel selection has happened, so clear start_disabled for the
incoming BSS before starting it.
