Subject: [PATCH 1/8] batman-adv: convert time_after instances to has_timed_out
To increase readability the has_timed_out() functions has been introduced.
This patch converts existing time_after() calls to use this wrapper
function (if applicable).
This patch also converts all timeouts to miliseconds to be consistent.
