hostapd: ucode: clear start_disabled when reloading a started BSS

On a radio shared with a STA every AP BSS is generated with
start_disabled=1. A smart reload that takes the full bss.set_config() path
restarts the BSS but never cleared start_disabled, so hostapd_start_beacon()
skipped beaconing and the AP went silently quiet until an unrelated
apsta_state event. Clear it when the BSS was already started, matching the
add_bss path.
