[klibc] vsscanf: remove unused variables
Removed unused local variable from vsscanf().
Signed-off-by: Greg Thelen <gthelen@google.com>
"POSIX is quite explicit that the unsigned
formats still accept signed input, and since klibc requires that signed
and unsigned integer types are the same the only reason to track it
would be to handle numeric overflow." -hpa
