tpl_wayland_egl_thread: Add necessity check for buffer release

On buffer release cb, there was no checking mechanism to check if this
buffer needs to be released or not.

This patch will add checking if this buffer has to be released or not.

Therefore, unnecessary buffer release cb will be detected and handled
correctly.
