SUNRPC: Use short-hand IPv6 ANYADDR for RPCB_SET
Clean up: When doing an RPCB_SET, make the kernel's rpcb client use the shorthand "::" for the universal form of the IPv6 ANY address. Without this patch, rpcbind will advertise: 0000:0000:0000:0000:0000:0000:0000:0000.x.y This is cosmetic only. It cleans up the display of information from /sbin/rpcinfo.
