[PATCH] daemon: remove unused $parent_pipe variable

[PATCH] daemon: remove unused $parent_pipe variable

[Eric Wong]

We can just create a ParentPipe and let PublicInbox::DS
manage its life cycle.  While we're at it, favor `\&coderef'
over `*coderef' so we're explicit about it being a code ref
and not some other ref type.
