Not sure this can happen, but seems like a reasonable sanity
check.
[shafi] possibly if the peer is removed and the bit is not cleared in the driver
? when the new peer occupies the slot
A firmware bug could cause this, but I never saw this WARN hit. Still seems like
a good sanity check to me, though...it would be quite hard to debug this sort of bug
if it actually did happen.
Thanks,
Ben
