Initialize variable to placate compiler.

Since commit 5883ff30b0, some compilers have been warning that the
rtekind variable in unique_nonjoin_rtekind() may be used
uninitialized.  There doesn't appear to be any actual risk, so
let's just initialize it to something to silence the compiler
warnings.
