From: Wenjing Liu <Wenjing.Liu at amd.com>

[why]
In HDCP Uninitialzed State, a CPIRQ event would cause log output
internal policy error because the CPIRQ event is not recognized as
unexpected event.

[how]
CPIRQ is issued in HDCP uninitialized state is unexpected.  We should
set unexpected event flag in event ctx.
