Revert "Warn if forked from the event loop during event_reinit()"

Thinking about this more and realizing that this was a mistake, so
should be reverted.

In a nut shell I guess most of the apps calls event_reinit() from the
loop (see [1] for example), and this should be totally fine (the bit
with the signals [2] handled in event_reinit() gracefully)

This reverts commit 497ef904d544ac51de43934549dbeccce8e6e8f8.
