random: use lockless method of accessing and updating f->reg_idx

[ Upstream commit 92e75428ffc90e2a0321062379f883f3671cfebe ]

Linus pointed out that there is a much more efficient way of avoiding
the problem that we were trying to address in commit 9dfa7bba35ac0:
"fix race in drivers/char/random.c:get_reg()".
