* Fix for two problems introduced by r10661:
1. ensure to use the key ''after'' it is initialized (sigh).
1. handle the case where we free the attrkey before it is fully
initialized (i.e., some other error causes us to free it). In
this case, don't try to remove the key from the hash map,
because it won't exist.
* More accurate zeroing in the keyval constructor
(ompi_attrkey_item_constructor)
* Widen the scope of the alock such that the attrkey destructor does
not need to acquire it. Instead, assume that the caller already
has it.
* Add a comment about why the keyval may get destroyed as the result
of deleting an attribute (so that I don't have to figure it out
again the next time I read this code :-) )
