[PATCH 5/7] mesh: allow processing authentication frames in blocked state

[Felix Fietkau]

If authentication fails repeatedly e.g. because of a weak signal, the link
can end up in blocked state. If one of the nodes tries to establish a link
again before it is unblocked on the other side, it will block the link to
that other side. The same happens on the other side when it unblocks the
link. In that scenario, the link never recovers on its own.

To fix this, allow restarting authentication even if the link is in blocked
state, but don't initiate the attempt until the blocked period is over.
