ocfs2/dlm: Retract fix for race between purge and migrate
Mainline commit d4f7e650e55af6b235871126f747da88600e8040 attempts to delay
the dlm_thread from sending the drop ref message if the lockres is being
migrated. The problem is that we make the dlm_thread wait for the migration
to complete. This causes a deadlock as dlm_thread also participates in the
lockres migration process.
A better fix for the original oss bugzilla#1012 is in testing.
