ping_manager() to prevent 'add' before 'remove' completes
It is currently possible to remove a device and re-add it without the
manager noticing, i.e. without detecting a mdstat->devcnt
container->devcnt mismatch. Introduce ping_manager() to arrange for
mdmon to run manage_container() prior to mdadm dropping the exclusive
open() on the container. Despite these precautions sysfs_read() may
still fail. If this happens invalidate container->devcnt to ensure
manage_container() runs at the next event.
