ocfs2/dlm: unlock lockres spinlock before dlm_lockres_put

ocfs2/dlm: unlock lockres spinlock before dlm_lockres_put

dlm_lockres_put will call dlm_lockres_release if it is the last
reference, and then it may call dlm_print_one_lock_resource and
take lockres spinlock.

So unlock lockres spinlock before dlm_lockres_put to avoid deadlock.
