Fix some near-bugs related to ResourceOwner function arguments

Browse Source 
These functions took a ResourceOwner argument, but only checked if it
was NULL, and then used CurrentResourceOwner for the actual work.
Surely the intention was to use the passed-in resource owner. All
current callers passed CurrentResourceOwner or NULL, so this has no
consequences at the moment, but it's an accident waiting to happen for
future caller and extensions.
