egl/wayland: do not leak wl_buffer when it is locked

Browse Source 
If color buffer is locked, do not set its wayland buffer to NULL;
otherwise it can not be freed later.

Rather, flag it in order to destroy it later on the release event.

v2: instruct release event to unlock only or free wl_buffer too (Daniel)

This also fixes dEQP-EGL.functional.swap_buffers_with_damage.* tests.
