Subject: [PATCH] wayland: Only cancel display read after prepare success

The display reader count only increments when wl_display_prepare_read
succeeds.  Calling wl_display_cancel_read when wl_display_prepare_read
has not succeeded results in a negative reader count, which does not
have well-defined behavior.
