Re: [PATCH net] net_sched: gact: Fix potential panic in tcf_gact().

gact_rand array is accessed by gact->tcfg_ptype whose value
is assumed to less than MAX_RAND, but any range checks are
not performed.

So add a check in tcf_gact_init(). And in tcf_gact(), we can
reduce a branch.

Applied and queued up for -stable, thanks.
