Subject: [PATCH] NFS: Set key construction data for the legacy upcall

This prevents a null pointer dereference when
nfs_idmap_complete_pipe_upcall_locked() calls complete_request_key().

Fixes a regression caused by commit 0cac12023 (NFSv4: Ensure that
idmap_pipe_downcall sanity-checks the downcall data).
