Ziye Yang 590b6e7507 nbd: Use async manner to stop nbd device.
Purpose: In order to free all the allocated resources.

Our current code uses sync behaviour, and it will not wait for all
the resources are freed if there is active I/Os, and thus we will
not free some resources, e.g., some fds will not be closed.
