[PATCH 5.13 143/151] locking/rtmutex: Use the correct rtmutex debugging config option

[Greg Kroah-Hartman]

From: Zhen Lei <thunder.leizhen@xxxxxxxxxx>

commit 07d25971b220e477eb019fcb520a9f2e3ac966af upstream.

It's CONFIG_DEBUG_RT_MUTEXES not CONFIG_DEBUG_RT_MUTEX.

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