video: fbdev: aty: do not leak uninitialized padding in clk to userspace
commit 8e75f7a7a00461ef6d91797a60b606367f6e344d upstream.
'clk' is copied to a userland with padding byte(s) after 'vclk_post_div'
field unitialized, leaking data from the stack. Fix this ensuring all of
'clk' is initialized to zero.
