Log:
Fixed panics that will occur during attempts to rescan ATA disk devices
(which occur after disk errors). The panic is due to attempts to acquire
the ATA channel lock multiple times (at different levels), with the second
attempt trying to sleep in an interrupt context. The fix is to indicate
to the other levels that we already have the lock.
The problem has been fixed in -current a different way and isn't portable
to -stable.
