[Qemu-block] [PATCH for-4.0? 8/7] nbd/client: Fix error message for server with unusable sizing

[Eric Blake]

Add a missing space to the error message used when giving up on a
server that insists on an alignment which renders the last few bytes
of the export unreadable.

We've already concluded that 5-7 are too risky for 4.0 (so qemu 4.0
NBD servers will have non-compliance issues in alignment corner cases,
although in fewer places than where 3.1 had similar bugs; and the 4.0
client is able to work around those non-compliance cases).  But I'd
still like a review on 1-3 and this patch 8, as trivial improvements
worth having in 4.0. I'm borderline on whether having patch 4 in 4.0
adds any value.
