Alexander Motin f2831a952d Avoid 256 integer divisions per rc4_init() call. Replace it with using
separate index variable.

It gives more then double rc4_init() performance increase on tested i386 P4.
It also gives about 15% speedup to PPTP VPN with stateless MPPE encryption
(by ng_mppc) which calls rc4_init() for every packet.
