hostapd: Clean up if interface setup fails

If for some reason interface setup fails mid-way when setting up
multi-BSS AP it was possible to get segmentation fault because driver
was not properly cleaned up.

One possible trigger, when using nl80211 driver, was udev renaming an
interface created by hostapd causing, e.g., linux_set_iface_flags() to
fail.
