update: stop ceph-crash service before upgrading

This adds the missing service stop task for ceph-crash upgrade workflow.

It should have been added through commit
`15872e3db1e342238636bc9c8e1aef6bd1d3dcd8` in stable-4.0 but at the time
we backported this patch ceph-crash wasn't implemented yet so the
ceph-crash related content in this patch was removed. Then, ceph-crash
has been implemented later so we are still missing this part of the patch in
stable-4.0.
