When net.core.optmem_max is not set high enough, a call to sendmsg() might fail with ENOBUFS. Currently this is treated as an error. When we have no more buffer space left, we should continue to process any completions and by doing so, free up the auxiliary buffers we ran out of. With this change I was able to run perf against the spdk target with a purposely set to a low, value of optmem_max, where previously it would fail.
