[PATCH] tools/memory-model: Remove lock-final checking in lock.cat

[Boqun Feng]

In commit 30b795df11a1 ("tools/memory-model: Improve mixed-access
checking in lock.cat"), we have added the checking to disallow any
normal memory access to lock variables, and this checking is stronger
than lock-final. So remove the lock-final checking as it's unnecessary
now.
