IB/rxe: Fix missing completion for mem_reg work requests

[ Upstream commit 375dc53d032fc11e98036b5f228ad13f7c5933f5 ]

Run the completer task to post a work completion after processing
a memory registration or invalidate work request. This covers the
case where the memory registration or invalidate was the last work
request posted to the qp.
