Nathan Hjelm c32d84154a coll/ml: fix leaks and close all the framework opened
It is essential to call mca_base_framework_close for every framework
that is opened. coll/ml was not doing this so neither bcol nor sbgp
were getting cleaned up. This commit fixes this omission.

Also fixed a leak caused by calling OBJ_DESTRUCT for something created
with OBJ_NEW. With these changes coll/ml appears to be valgrind clean.

cmr=v1.8.2:reviewer=manjugv

This commit was SVN r31743.
