libdiskfs: Factorize code for last hard reference being released

* libdiskfs/node-lastref.c: New file
* libdiskfs/Makefile (OTHERSRCS): Add node-lastref.c
* libdiskfs/libdiskfs/node-nput.c (diskfs_nput): Replace last hard reference
code with a call to _diskfs_lastref.
* libdiskfs/node-nrele.c (diskfs_nrele): Likewise.
