Eric Blake 08ace1d753 nbd: Don't crash when server reports NBD_CMD_READ failure ...

If a server fails a read, for example with EIO, but the connection
is still live, then we would crash trying to print a non-existent
error message in nbd_client_co_preadv().  For consistency, also
change the error printout in nbd_read_reply_entry(), although that
instance does not crash.  Bug introduced in commit f140e300.
