vo_opengl: context_vdpau: minor fixes

Don't assume 0 is an invalid object handle. vdpau with its weird API
design makes all objects indexes, with 0 being a perfectly valid and
common value. You need to use VDP_INVALID_HANDLE, which is not 0.

Don't crash if init fails at vdpau initialization. It's because
mp_vdpau_destroy(NULL) crashes. Simplify it.

Destroy output surface backed FBO before output surface. Also, strictly
bookkeep the map/unmap calls (and unmap surfaces before destroying the
FBO/texture). I can't see a change in the weird errors when resizing the
window, but I guess it's slightly more correct.

Add the GL_WRITE_DISCARD_NV symbol to header_fixes.h, because we might
fail compilation with headers that do not contain the vdpau extension
(well, probably doesn't matter).
