OBTW, there's a nit on that memcpy, too. The r_addr is an array, so

memcpy(&map->r_addr

is passing the address of the array as a char **. It's the same as
map->r_addr, but technically the wrong type.

SUNRPC: Fix generation of universal addresses for

Fix some problems with rpcbind v3 and v4 queries from the in-kernel rpcbind
client:

1.  The r_addr argument must be a full universal address, not just an IP
address, and

2.  The universal address in r_addr is the address of the remote rpcbind
server, not the RPC service being requested

This addresses bugzilla.kernel.org report 8891 for 2.6.23-rc and greater.

In addition, if the rpcbind client is unable to start the rpcbind request,
make sure not to leak the xprt.
