MFC r319852:

Fix buffer lengths.

After r319369, the RPC code validates caller supplied buffer length in
taddr2uaddr.  When no -h is specified, the sizeof(ai_addr) is used,
which is always smaller than the required size and therefore uaddr
would be NULL, causing the kernel to copyin() from userland NULL
and fail with EFAULT.
