Use refcount_t for peropen reference counting in libnetfs.

* libnetfs/netfs.h: Use refcount_t.
* libnetfs/make-peropen.c: Initialize to 1 with refcount_init just like in libdiskfs.
* libnetfs/make-protid.c: Don't increment the count here. Do it like libdiskfs.
* libnetfs/io-duplicate.c: Add refcount_ref since netfs_make_protid no longer increments the refcount.
* libnetfs/io-reauthenticate.c: Likewise.
* libnetfs/io-restrict-auth.c: Likewise.
* libnetfs/release-peropen.c: Dereference without locking.
