The GstMemory objects contained in a GstBuffer could be replaced by an upstream element, which would break the association beteen the GstBuffer and the wayland wl_buffer, make the cache lookup results incorrect. This patch changes the cache lookup to use the first GstMemory in a buffer instead. For multi-plane buffers, this assumes that all of the GstMemory(s) will always be moved together as a set, and that the same (first) GstMemory isn't used with different combinations of other GstMemory(s).
