[Qemu-devel] [PATCH] nbd-client: Use correct macro parenthesization

[Eric Blake <eblake@redhat.com>]

If 'bs' is a complex expression, we were only casting the front half
rather than the full expression.  Luckily, none of the callers were
passing bad arguments, but it's better to be robust up front.

I plan to take this through my NBD queue, unless it is picked up
by qemu-trivial first...
