knav_dev_lock_held() is a single-use wrapper around
lockdep_is_held(&knav_dev_lock), used only as the lockdep condition
in for_each_handle_rcu. When CONFIG_PROVE_RCU_LIST is disabled,
list_for_each_entry_rcu() elides the condition argument entirely,
causing clang to report the macro as unused with W=2:
knav_qmss_queue.c:30:9: warning: macro is not used [-Wunused-macros]
30 | #define knav_dev_lock_held() \
Remove the intermediate macro and open-code lockdep_is_held() directly
in the for_each_handle_rcu definition.
