EGL 1.4 Specification says that
eglMakeCurrent(display, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT)
can be used to release the current thread's ownership on the surfaces
and context.
MESA's egl implementation was only accepting the parameters when the
KHR_surfaceless_context extension is supported.
