NFSv4.1/flexfiles: Fix freeing of mirrors
Mirrors are now shared objects, so we should not be freeing them directly inside ff_layout_free_lseg(). We should already be doing the right thing in _ff_layout_free_lseg(), so just let it handle things. Also ensure that ff_layout_free_mirror() frees the RPC credential if it is set. Fixes: 28a0d72c6867 ("Add refcounting to struct nfs4_ff_layout_mirror") Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
