MINOR: server: pass the server and thread to srv_migrate_conns_to_remove()

Browse Source 
We'll need to have access to the srv_per_thread element soon from this
function, and there's no particular reason for passing it list pointers
so let's pass the server and the thread so that it is autonomous. It
also makes the calling code simpler.
