My preference would be to fix it the opposite way, by
checking and ignoring zcache_host in zcache_put_pool.
The ref-counting is to ensure that a client isn't
accidentally destroyed while in use (for multiple-client
users such as ramster and kvm) and since zcache_host is a static
struct, it should never be deleted so need not be ref-counted.

If we do that, we'll need to comment it.  If we don't, it won't be
obvious why we are refcounting every zcache client except one.  It'll
look like a bug.
