vdev_file_io_start() to use taskq_dispatch(TQ_PUSHPAGE)
The vdev_file_io_start() function may be processing a zio that the
txg_sync thread is waiting on. In this case it is not safe to perform
memory allocations that may generate new I/O since this could cause a
deadlock. To avoid this, call taskq_dispatch() with TQ_PUSHPAGE
instead of TQ_SLEEP.
