locking/rwsem: Move is_rwsem_reader_owned() and rwsem_owner() under CONFIG_DEBUG_RWSEMS
Both is_rwsem_reader_owned() and rwsem_owner() are currently only used when
CONFIG_DEBUG_RWSEMS is defined. This causes a compilation error with clang
when `make W=1` and CONFIG_WERROR=y:
kernel/locking/rwsem.c:187:20: error: unused function 'is_rwsem_reader_owned' [-Werror,-Wunused-function]
187 | static inline bool is_rwsem_reader_owned(struct rw_semaphore *sem)
| ^~~~~~~~~~~~~~~~~~~~~
kernel/locking/rwsem.c:271:35: error: unused function 'rwsem_owner' [-Werror,-Wunused-function]
271 | static inline struct task_struct *rwsem_owner(struct rw_semaphore *sem)
| ^~~~~~~~~~~
Fix this by moving these two functions under the CONFIG_DEBUG_RWSEMS define.
