Drop unnecessary NULL check in frame_callback_handle_done()
After wl_callback_destroy() is called, frame_callback_handle_done()
is guaranteed to never be called by libwayland: the done event will
be silently dropped instead.

And better behave when multiple configure events are received.
Fix build error due to decl after case
Fixes the following error:
../main.c:267:4: error: expected expression
char *end = NULL;
Fix return value after input event
Add -d option to specify delay
