Sergey Sharybin 9921e10583 Math: Set matrix to zero when inversion fails
Avoids usage of uninitialized memory when inversion fails.

That uninitialized memory can cause object to become visible when
it is supposed not to or other artifacts like that.

Longer term solution would be to check every instance of invert_m#
function and to explicit fallback when needed (possibly, using
extra utility functions).
