Change checking rule in startArcAction(false) for HDMI CTS

[Description]
For HDMI CTS Certification:
    HEACT 5-15: IEC 60958-1 Stream Verification

Before sending <Request ARC initiation> or <Request ARC termination>
CEC frameworks checks whether the port connected AVR is valid
 - if it's connected to ARC port
 - if it's adjacent to TV

If AVR changes its PA from valid to non-adjacent
(E.g. ARC port : 1.0.0.0 is valid, it changes to 1.1.0.0)
With the current framework design, <Request ARC Termination>
won't be sent.

However, <Request ARC Termination> should still be sent
to pass this test item.

We should not consider whether the port is direct connected
or not when startArcAction(false)
We should always send <Request ARC termination> for this case.

Test: Pass HEACT 5-15: IEC 60958-1 Stream Verification
