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

This reverts commit ea5d404655ba ("vhost: fix release path lockdep
checks")

In commit 47283bef7ed3 ("vhost: move memory pointer to VQs"), RCU
operations have been replaced by mutex, we need to remove the no longer
used `locked' parameter by reverting original patch.
