Funny you mention this, while I was hunting for the root cause of the problem, 
I had a patch which did just that, adding a pid struct to the audit_field 
struct.  Eventually we will have to go that route as (sadly) a PID is no 
longer sufficient to identify a process on the system, you need PID+ns.  We'll 
still have the find_pid() problem then, but there are ways around that by 
being smarter about how we add/delete/store filtering rules.

I opted for the patch I posted here because as you point out we really only 
work in the init namespace and it didn't muddle the bugfix with new 
functionality.
