[dpdk-stable] [PATCH v3 1/8] vhost: fix virtio ready flag check

[Adrian Moreno]

From: Maxime Coquelin <maxime.coquelin at redhat.com>

Before checking whether the device is ready is done
a check on whether the RUNNING flag is set. Then the
READY flag is set if virtio_is_ready() returns true.

While it seems to not cause any issue, it makes more
sense to check whether the READY flag is set and not
the RUNNING one.

Fixes: c0674b1bc898 ("vhost: move the device ready check at proper place")
