[Qemu-devel] [PATCHv2 09/14] nbd: don't change socket block during negotiate

["Marc-André Lureau" <marcandre.lureau@gmail.com>]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

The caller might handle non-blocking using coroutine. Leave the choice
to the caller to use a blocking or non-blocking negotiate.
