Changpeng Liu 830f7e7907 vhost: add non-blocking API for posting interrupt 
Vhost-user library locks all VQ's access lock when processing
vring based messages, such as SET_VRING_KICK and SET_VRING_CALL,
and the data processing thread may already be started, e.g: SPDK
vhost-blk and vhost-scsi will start the data processing thread
when one vring is ready, then deadlock may happen when SPDK is
posting interrupts to VM.  Here, we add a new API which allows
caller to try again later for this case.
