Trond Myklebust e6efe9b152 pNFS/flexfiles: Fix list corruption if the mirror count changes 
commit 8b04013737341442ed914b336cde866b902664ae upstream.

If the mirror count changes in the new layout we pick up inside
ff_layout_pg_init_write(), then we can end up adding the
request to the wrong mirror and corrupting the mirror->pg_list.

Fixes: d600ad1f2b ("NFS41: pop some layoutget errors to application")
