drivers/video/via/ioctl.c: prevent reading uninitialized stack memory
The VIAFB_GET_INFO device ioctl allows unprivileged users to read 246
bytes of uninitialized stack memory, because the "reserved" member of
the viafb_ioctl_info struct declared on the stack is not altered or
zeroed before being copied back to the user. This patch takes care of
it.
