Subject: libdiskfs: lock-less reference counting for peropen objects

* libdiskfs/diskfs.h (struct peropen): Use refcount_t for field refcnt.
* libdiskfs/peropen-make.c (diskfs_make_peropen): Initialize refcnt.
* libdiskfs/peropen-rele.c (diskfs_release_peropen): Adjust accordingly.
* libdiskfs/protid-make.c (diskfs_start_protid): Likewise.  Also, the
node must no longer be locked, adjust comment accordingly.
(diskfs_create_protid): Likewise.
