resource: display: Fix error when get_fps_info return null

When enlightenment doesn't draw the anything, get_fps_info of enlightenment
doesn't return the fps information with null. DISPLAY_FPS returns the 0.0
for handling this case.

And add RESOURCE_DRIVER_NO_DEVICE flag to display resource driver.
