[ewg] [PATCH 3/5 try2] ib/ehca: repoll on invalid opcode

When the ehca driver detects an invalid opcode in a CQE, it currently passes
the CQE to the application and returns with success. This patch changes the
CQE handling to discard CQEs with invalid opcodes and to continue reading the
next CQE from the CQ.
