nbd: silence maybe-uninitialized warnings 

gcc 10 from Fedora 32 gives me:

Compiling C object libblock.fa.p/nbd_server.c.o
../nbd/server.c: In function ‘nbd_co_client_start’:
../nbd/server.c:625:14: error: ‘namelen’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
  625 |         rc = nbd_negotiate_send_info(client, NBD_INFO_NAME, namelen, name,
      |              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  626 |                                      errp);
      |                                      ~~~~~
../nbd/server.c:564:14: note: ‘namelen’ was declared here
  564 |     uint32_t namelen;
      |              ^~~~~~~
cc1: all warnings being treated as errors

As I cannot see how this can happen, let uns silence the warning.
