Subject: [PATCH] liboverlay: set correct flags for external display channel

When external display is connected during video playback, the
flags to overlay was not set properly.
Pass the flags which comes from the hwc, by just changing the
WAIT_FOR_VSYNC(external should not wait for vsync)

(cherry picked from commit 857cfcba2d120d5da4916c7cb4fe119a08d1ce68)
