dpif-linux: Remove poll_fd_woke() optimization from dpif_linux_recv().

This optimization on its own provided about 37% benefit against a
load of a single netperf CRR test, but at the same time it penalized
ovs-benchmark by about 11%.  We can get back the CRR performance
loss, and more, other ways, so the first step is to revert this
patch, temporarily accepting the performance loss.
