USB: remove USB_QUIRK_NO_AUTOSUSPEND

This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk.  Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended.  Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID.  I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.

The patch also cleans up the hasty way in which autosuspend gets
disabled.  Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ.  It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.
