Linux Virtualization - Apr 2015 - [PATCH] Revert "vhost: fix release path lockdep checks"

This reverts commit ea5d404655ba3b356d0c06d6a3c4f24112124522.

In commit 47283bef7ed356629467d1fac61687756e48f254(vhost: move memory
pointer to VQs), rcu_ operation has been replaced by mutex, and original
issue fixed in sea5d404655 has gone as well, we need to remove the
no-longer-used `locked' var by reverting the orignal patch.
