nl80211util: refactor nl80211_parse_attrs for nested variant
To prep for adding a _nested() variant of this function refactor this to act on an l_genl_attr object rather than the message itself. In addition a handler specific to the attribute being parsed is now passed in, with the current "handler_for_type" being renamed to "handler_for_nl80211" that corresponds to root level attributes.
