[Qemu-block] [PATCH] xen: Fix format string

[Philippe Mathieu-Daudé]

Trivial format string fix to solve:

  hw/block/xen-block.c: In function 'xen_block_realize':
  hw/block/xen-block.c:218:53: error: format '%lu' expects argument of type 
'long unsigned int', but argument 4 has type 'int64_t {aka long long int}' 
[-Werror=format=]
      xen_device_backend_printf(xendev, "sectors", "%lu",
                                                      ^
                                blk_getlength(conf->blk) /
                                conf->logical_block_size);

blk_getlength() returns an int64_t.
