dlm: use idr_for_each_entry() in recover_idr_clear() error path
Tejun Heo [Thu, 28 Feb 2013 01:03:44 +0000 (17:03 -0800)]
Convert recover_idr_clear() to use idr_for_each_entry() instead of
idr_for_each().  It's somewhat less efficient this way but it shouldn't
matter in an error path.  This is to help with deprecation of
idr_remove_all().
