Remove warning when associated display is ADISPLAY_ID_NONE. 



This warning caused logspam in emulator system image because emulator
host pre-registeris several touch screen devices which are not associated
with any display until multi-display feature is turned on. Unfortunately,
there is no easy way to add/remove touch screen device on-demand in
emulator host at runtime.
