ply-device-manager: verify_add_or_change(): Move local_console_is_text check

Move the local_console_is_text check outside of the
"if (subsytem == SUBSYSTEM_DRM)" block.

This check is equally relevant for SUBSYSTEM_FRAME_BUFFER.

Note by itself this is a no-op since verify_add_or_change() *always*
returns false for SUBSYSTEM_FRAME_BUFFER devices.

This is a preparation patch for making verify_add_or_change() not
return false when manager->device_timeout_elapsed is set.
