Update the order in which we apply new proc_state/oom_adj values.

We check if the network blocked state (which depends on proc_state)
of an uid changed and update a seq counter to keep track of that.
We need to do this before the newly computed proc_state/oom_adj
values are applied. It used to be like this earlier but seems there
was a regression.
