Subject: [PATCH] ppp: Destroy the mutex when cleanup
Git-commit: f02b2320b27c16b644691267ee3b5c110846f49e
Patch-mainline: v4.15-rc1
References: bsc#1051510
The mutex_destroy only makes sense when enable DEBUG_MUTEX. For the
good readbility, it's better to invoke it in exit func when the init
func invokes mutex_init.
