libdiskfs: fix removal of socket nodes
When the file system supports ifsock shortcuts, a socket node can obtain
a right on a socket address. This reference is only lost if the address
is destroyed, through a dead-name notification. On the other hand,
pflocal keeps the address around until all references are dropped. This
leads to a situation where socket nodes, addresses, and their associated
sockets are leaked. To remedy the situation, make addresses get a light
reference on socket nodes, and properly deallocate it when the node is
destroyed, which will in turn make pflocal correctly remove the matching
address and socket.
* libdiskfs/ifsock.c (diskfs_S_ifsock_getsockaddr): Add a light reference
instead of a hard one.
* libdiskfs/node-nput.c (diskfs_nput): Deallocate right to socket address
when cleaning light references.
