matroskadec: don't warn about unknown spherical medata when none is present 

track->video.projection.type is set to 0 (a Matroska specific "No spherical
metadata present" value, with no related AVSphericalMapping) by default on
files without the element.

This removes bogus warnings on every single matroska file without Spherical
metadata.
