[Qemu-devel] [PATCH stable-1.4 v2 3/4] qemu-socket: set passed fd non-blocking in socket_connect()

[Stefan Hajnoczi <stefanha@redhat.com>]

socket_connect() sets non-blocking on TCP or UNIX domain sockets if a
callback function is passed.  Do the same for file descriptor passing,
otherwise we could unexpectedly be using a blocking file descriptor.
