As part of commit efb39a5, the account reaper grew a bind_port
attribute, but it wasn't being converted to int, so naturally "6002"
!= 6002, and it wouldn't reap anything.
The bind_port was only used for determining the local devices. Rather
than fix the code to call int(), this commit removes the need for
bind_port entirely by skipping the port check. If your rings have IPs,
this is the same behavior as pre-efb39a5, and if your rings have
hostnames, this still works.
