Stop sending object handle with sendObject request.

According to the MTP spec, the sendObject request must follow
sendObjectInfo request and we could not send an object handle with
sendObject request. The CL stops sending object handle with a sendObject
request. Instead it checks if the given object handle equals to the
object handle returned by the previous sendObjectInfo request.

Bug: 31918048
Test: manually invoked sendObjectInfo and sendObject.
