rpc: xdr_truncate_encode
This will be used in the server side in a few cases:
- when certain operations (read, readdir, readlink) fail after
encoding a partial response.
- when we run out of space after encoding a partial response.
- in readlink, where we initially reserve PAGE_SIZE bytes for
data, then truncate to the actual size.
