[Cluster-devel] [PATCHv2 dlm-next 01/13] fs: dlm: add missing spin_unlock

This patch fixes commit dc52cd2eff4a ("fs: dlm: fix F_CANCELLK to cancel
pending request") that we don't unlock the ops_lock in a rate case when
a waiter cannot be found. This case can only happen when cancellation of
plock operation was successful but no kernel waiter was being found.
