4.1-stable review patch. If anyone has any objections, please let me know.
------------------ From: Trond Myklebust <trond.mykleb...@primarydata.com> commit 03d5eb65b53889fe98a5ecddfe205c16e3093190 upstream. If the function exits early, then we must put those requests that were not processed back onto the &mirror->pg_list so they can be cleaned up by nfs_pgio_error().
