    _______________________________________________________

Details:

Current implementation iterates the lowpan6_data.reass_list every time
dequeue_datagram() is called.
We can get previous lrh in all the context calling dequeue_datagram().
By adding a prev arguemnt to dequeue_datagram(), we can speed up the dequeue
datagram process.

All the callers never check return value of dequeue_datagram() as it always
return ERR_OR, thus make it return void instead.

PS.
I cannot test this patch so post it here for review.
Appreciate if someone can test it.
