Joshua Hursey 0a09f8bc51 coll/hcoll: Protect module destruct when not fully initialized

* If hcoll is given a negative priority, but not enabled=0 then
   the module is constructed, but then destructed before calling
   it's query(). So the previous pointers are not initialized.
   If we try to OBJ_RELEASE them in a debug build an assert will fire.
   This commit adds some protection against that and initializes
   the _module pointers to NULL.

ompi/coll: Fix warnings in hcoll component

coll_hcoll_debug.h

Per the details and schedule outlined in the attached RFC, Mellanox Technologies would like to CMR the new 'coll/hcoll' component. This component enables Mellanox Technologies' latest HPC middleware offering - 'Hcoll'. 'Hcoll' is a high-performance, standalone collectives library with support for truly asynchronous, non-blocking, hierarchical collectives via hardware offload on supporting Mellanox HCAs (ConnectX-3 and above.) To build the component, libhcoll must first be installed on your system, then you must configure OMPI with the configure flag: '--with-hcoll=/path/to/libhcoll'. Subsequent to installing, you may select the 'coll/hcoll' component at runtime as you would any other coll component, e.g. '-mca coll hcoll,tuned,libnbc'. This has been reviewed by Josh Ladd and should be added to cmr:v1.7:reviewer=jladd
