drivers/video/sis/sis_main.c: prevent reading uninitialized stack memory
The FBIOGET_VBLANK device ioctl allows unprivileged users to read 16 bytes
of uninitialized stack memory, because the "reserved" member of the
fb_vblank struct declared on the stack is not altered or zeroed before
being copied back to the user. This patch takes care of it.
