Paolo Bonzini 7fe7b68b32 nbd: do not block in nbd_wr_sync if no data at all is available ... Right now, nbd_wr_sync will hang if no data at all is available on the socket and the other side is not going to provide any. Relax this by making it loop only for writes or partial reads. This fixes a race where one thread is executing qemu_aio_wait() and another is executing main_loop_wait(). Then, the select() call in main_loop_wait() can return stale data and call the "readable" callback with no data in the socket.
