Yes, I'm not too excited about handling the AERs in kernel space,
having a userspace daemon to listen for them would generally be more
useful.

The only exception is the namespace changed AER that we already handle.
But while we're at it: why do we make use of the changed namespace
list log page in this case instead of doing a full recan.
