rua: RUA_Disc_Ind only when CLIENT is connected
Only dispatch RUA_Disc_Ind to CLIENT when CLIENT is connected.
Reason:
If a test does not care much about conn cleanup, it may cause a
situation where the CLIENT has already disconnected when osmo-hnbgw
sends a RUA Disconnect. A disconnected CLIENT port will cause the final
verdict to become 'error'. Instead, if the CLIENT is already
disconnected, just don't bother, and allow tests to still pass.
This will become necessary, because:
So far a RUA Disconnect without any RANAP payload is not detected by the
RUA emulation. But patch Ia0b89e9198794d196a88040ee89bdf24f3b08ae0 will
fix it, so that *every* RUA Disconnect causes a RUA_Disc_Ind sent to the
CLIENT. From then on, we will see a bunch more RUA_Disc_Ind at the end
of tests. Some of those happen *after* the client already disconnected,
causing tests to error that have been passing for a long time.
