Move all the owner setting code closer to the rwsem-xadd fast paths directly within rwsem.h file as well as in the slowpaths where owner setting is done after acquring the lock. This will enable us to add DEBUG_RWSEMS check in a later patch to make sure that read lock is really acquired when rwsem_down_read_failed() returns, for instance.
