"fb_lock_print -c" hangs server

Environment: linux

 Description  « Hide
Lock print remaps robust shared mutex betwen different memory locations. This probably violates posix rules that say "mutex, returned by pthread_mutex_init, can't be copied to another location", though not explicitly. On attempt to unlock such remapped mutex linux returns no error, but does not release mutex.

FB3 does not require fixing - remapping was fixed during general code cleanup
