[OMPI devel] Fix compiler warnings in FT code

[Adrian Reber]

I have a simple patch which fixes the remaining compiler warnings when
running with '--with-ft':

https://lisas.de/git/?p=open-mpi.git;a=commitdiff;h=4dee703a0a2e64972b0c35b7693c11a09f1fbe5f

Does anybody see any problems with this patch?
