The following ugly hack to the exit path of nfs_readlinkrpc() circumvents
an Auspex bug: for symlinks longer than 112 (0x70) they return a 1024 byte
xdr string - the correct data with many nulls appended. Without this fix
namei returns ENAMETOOLONG, at least it does on our source base and on
FreeBSD 3.0. Note we do not (and should not) rely upon their null padding.
