ANDROID: rcu_sync: Export rcu_sync_lockdep_assert

Browse source 
x86_64:allmodconfig fails to build with the following error.

ERROR: "rcu_sync_lockdep_assert" [kernel/locking/locktorture.ko] undefined!

Introduced by commit 3228c5eb7a ("RFC: FROMLIST: locking/percpu-rwsem:
Optimize readers and reduce global impact"). The applied upstream version
exports the missing symbol, so let's do the same.

Change-Id: If4e516715c3415fe8c82090f287174857561550d
Fixes: 3228c5eb7a ("RFC: FROMLIST: locking/percpu-rwsem: Optimize ...")
