Subject: [PATCH 14/26] staging/lustre/ptlrpc: skip rpcs that fail ptl_send_rpc

From: Keith Mannthey <keith.mannthey@...el.com>

ptl_send_rpc is not dealing with -ENOMEM in some
situations.  When the ptl_send_rpc fails we need
set error and skip further processing or trigger
and LBUG

Original patch from Peng Tao.
