kernel: vt: prevent kernel-infoleak in con_font_get()

In the Linux kernel, the following vulnerability has been resolved: vt: prevent kernel-infoleak in confontget font.data may not initialize all memory spaces depending on the implementation of vc-vcsw-confontget. This may cause info-leak, so to prevent this, it is safest to modify it to initialize...
