There were some major, and some minor bugs having to do with
the reference counting of node devices in daemon/remote.c.
Some functions were completely failing to unreference node devices;
this would lead to many open file descriptors, which would eventually
fail.
The minor bugs were along the same lines, but were in rarely
used error paths.
