Fix bug with --compare-dest option where missing parent directories in the

target destination were not getting created.  There was a case in
receiver.c to do that but it was only getting invoked when the -R option is
specified, although I don't know why it was limited to that.

It's too bad I didn't get a chance to more fully test the use of
--compare-dest by my nsbd program before releasing rsync 2.3.0.  I'll
probably need to put a workaround in nsbd too until the next release
of rsync.
