pNFS/flexfiles: Fix list corruption if the mirror count changes
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: d600ad1f2bdb ("NFS41: pop some layoutget errors to application")
