[dpdk-stable] [PATCH 02/15] vhost: configure vDPA as soon as the device is ready

[Maxime Coquelin]

There might not have any VHOST_USER_SET_VRING_CALL requests
sent once virtio device is ready. When it happens, the vDPA
device's dev_conf() callback may never be called.

Fixes: 9f9014512822 ("vhost: configure vDPA device after set vring call message")
