x86/ldt: Make a size argument unsigned My static checker complains that we put an upper bound on the "size" argument but not a lower bound. The checker is not smart enough to know the possible ranges of "old_mm->context.ldt->size" from init_new_context_ldt() so it thinks maybe it could be negative. Let's make it unsigned to silence the warning and future proof the code a bit.
