Fix HWC2to1Adapter crashing dragon at startup
Some devices such a dragon(ryu) do not start with a valid active
configuration id (e.g: -1). This is unexpected from HWC2to1Adapter
and resulted in crash at startup when switching the device from HWC1
to HWC2 with adapter.
This patch detects this at startup and put the device in an expected
configutation using the first configuration index (0).
Test: Tested on ryu
