Camera: Fix OutputConfiguration equality check

For the non deferred configuration, equals() and hashCode() show
different behavior when the number of surfaces changes.
Thus, the camera device could try to create a stream using an already
configured surface.

This patch fixed the issue by checking the size of surface list in
equals() for the non deferred configuration.
