ATA tag queuing broken...

[Sean Chittenden]

Alright, well it's apparently no surprise to folks that ATA tag queuing
is broken at the moment.  Are there any objections to me adding a few
cautious words to ata(4) and tuning(7) that advise _against_ the use
of ata tag queuing given that they're likely the fastest way to reboot
a -STABLE box?

Here's a PR that I tacked a tad bit of info into:
