vlib: fix counter_will_expand prediction
vlib_validate_combined_counter_will_expand() was calling
_vec_resize_will_expand() with wrong arguments, which resulted in false
return value. Apart from the initial call, it never indicated a vector
resize.
The callers relying on this function did not perform a barrier sync
because of the wrong prediction even if the vector got extended by
a subsequent vlib_validate_combined_counter() call.
The fix introduces a new, simplified macro that is easier to call.
vec_resize_will_expand() accepts the same arguments as vec_resize().
Type: fix
