Eric Blake d1e2c3e7bd nbd/server: Reject embedded NUL in NBD strings
The NBD spec is clear that any string sent from the client must not
contain embedded NUL characters.  If the client passes "a\0", we
should reject that option request rather than act on "a".

Testing this is not possible with a compliant client, but I was able
to use gdb to coerce libnbd into temporarily behaving as such a
client.
