Eliminate less-than-zero checks for unsigned variables.
According to section 4.1.5 of C89 standard, size_t is an unsigned
type. These checks were found with 'cppcheck' static analysis tool.

must not cast it to unsigned long, which may be shorter than
VALUE, and the result can be mere garbage.

RB_GC_GUARD() is only for variables on the machine stack, because it
forces a VALUE to be stored in a variable which should be referenced
from the GC, but does not add any reference path to the variable.
So it makes no sense for objects in heap.
