Fix segmentation fault during network tranfer

Since 'chunk' which is unit of transfer is not initialized, aio_read()
is failed with invalid argument error. Moreover, in this case,
chunk.nh is even NULL, so chunk->nh->sock_fd cause segmentation fault.
Thus, this patch fixes to initialize chunk properly, and make chunk.nh
have network handler pointer.
