Actually not necessary to have a finalize pointer in the module

struct; the coll base will have the mca_coll_t's from all the modules
who said that they can run, and that has a finalize() method pointer
in it (and this makes it uniform for the modules -- the finalize()
method will *always* be called after query(); the init() function
simply will not be invoked if the module was not selected).
