BUG/MINOR: spoe: Properly switch SPOE filter to WAITING_ACK state

When the SPOE applet is created, the SPOE filter is set in SENDING_MSGS
state. When the applet has transferred data, it should switch the filter to
WAITING_ACK state. Concretly, there is no bug. At best, it could save some
useless applet wakeups.

This patch should be backported as far as 3.1
