egl/dri2: avoid undefined unlocks

unlocks were incorrectly added to paths using dri2_egl_display() as
well as those using dri2_egl_display_lock()

pthread_mutex_unlock() when unlocked is documented by posix as
being undefined behaviour.  On OpenBSD pthread_mutex_unlock() will call
abort(3) if this happens.
