sparc64: make string buffers large enough

commit b5c3206 upstream. My static checker complains that if "lvl" is ULONG_MAX (this is 64 bit) then some of the strings will overflow. I don't know if that's possible but it seems simple enough to make the buffers slightly larger. Signed-off-by: Dan Carpenter <[email protected]> Signed-off-by: David S.
