e_comp_wl: break from meaningless loop
e_comp_wl: break from meaningless loop

Summary:
kbd.keys are only added from e_comp_wl_key_down().
         And in that function, duplicated keys are not add in the list.
         So only one key is going to be in the list.

Test Plan: Watch kbd.keys list during key press / release.
