block: sunvdc: don't run hw queue synchronously from irq context
vdc_blk_queue_start() may be called from irq context, so we can't run
queue via blk_mq_start_hw_queues() since we never allow to run queue
from irq context. Use blk_mq_start_stopped_hw_queues(q, true) to fix
this issue.
Fixes: fa182a1fa97dff56cd ("sunvdc: convert to blk-mq")
