Remove extra indentation level from hostapd_config_fill()

Remove extra indentation level from hostapd_config_fill()

The configuration file parsing routines were moved to a separate
function a while back, but left at the old indentation level to avoid
showing large diffs in the commit and to avoid conflicts with parallel
development in other branches. There is never a perfect time for this
type of changes, but we might as well finally get rid of that extra
indentation now with Hotspot 2.0 Rel 2 changes pulled in.
