[PATCH] mesh: Use appropriate BLOCKED state duration

[Masashi Honma]

Previously, BLOCKED state duration slightly increased up to 3600. Though
the BLOCKED state could be canceled by ap_handle_timer(). Because the
timer timeouts in ap_max_inactivity(default=300sec) and remove sta
objects (the object retains BLOCKED state).

This patch re-design my commit bf51f4f82bdb50356de5501acac53fe1b91a7b86
to replace mesh_auth_block_duration by ap_max_inactivity and remove
incremental duration.
