[PATCH 6/9] random: simplify accounting logic

This logic is exactly equivalent to the old logic, but it should be easier to see what it's doing. The equivalence depends on one fact from outside this function: when 'r->limit' is false, 'reserved' is zero. (Well, two facts; the other is that 'reserved' is never negative.) Cc: "Theodore Ts'o"
