[PATCH] fix comment for printk rate limiting

[Uwe Kleine-KÃnig]

The comment assumed the burst to be one and the ratelimit used to be named
printk_ratelimit_jiffies.

Hello,

The comment was already wrong before commit

	717115e... printk ratelimiting rewrite

but I selected the Cc: list from this commit.

@trivial: I already sent a patch that updates the comment to the state before
717115e.  You probably should drop this now as it became wrong.

Best regards
Uwe
