Cleanup DB_DNODE() macros usage

Browse Source 
- Use the macros in few places it was missed.
 - Reduce scope of DB_DNODE_ENTER/EXIT() and inline some DB_DNODE()
uses to make it more obvious what exactly is protected there and
make unprotected accesses by mistake more difficult.
 - Make use of zrl_owner().
