kmssink: Save last metadata at the same time as the last buffer

Browse source 
The render width/height and the vinfo was only saved upon renegotiation. This
fixes the problem by saving this metadata at the same time the buffer is
saved. The saved copy of this is needed for expose() and drain() virtual functions.
This fixes various assertion that happens on drain query.
