Suppress compiler warnings from commit ee895a655.
For obscure reasons, some buildfarm members are now generating
complaints about plpgsql_call_handler's "retval" variable possibly
being used uninitialized. It seems no less safe than it was before
that commit, but these complaints are (mostly?) new. I trust that
initializing the variable where it's declared will be enough to
shut that up.
I also notice that some compilers are warning about setjmp clobber
of the same variable, which is maybe a bit more defensible. Mark
it volatile to silence that.
Also, rearrange the logic to give procedure_resowner a single
point of initialization, in hopes of silencing some setjmp-clobber
warnings about that. (Marking it volatile would serve too, but
its sibling variables are depending on single assignment, so let's
stick with that method.)
