video: fix crash with vdpau when reinitializing rendering
Using vdpau will allocate additional textures for the reinterleaving
step, which uninit_rendering() will free. This is a problem because the
hwdec image remains mapped when reinitializing, so the reinterleaving
textures are turned into dangling pointers. Fix this by freeing the
reinterleave textures on full uninit instead.

Fixes #5447.
