Subject: [PATCH] locking/rtmutex: Add the missing 'ES' of macro CONFIG_DEBUG_RT_MUTEXES

The build option name is defined as DEBUG_RT_MUTEXES in lib/Kconfig.debug,
commit f41dcc18698e ("locking/rtmutex: Move debug functions as inlines
into common header") can also corroborate this.

Fixes: f7efc4799f81 ("locking/rtmutex: Inline chainwalk depth check")
