LU-2675 obd: decruft md_enqueue() and md_intent_lock()

Remove the lmm and lmmsize parameters from both functions, storing
that data in md_op_data when needed. Remove the unused lookup_flags
parameter from md_intent_lock(), and the unused reqp parameter from
md_enqueue(). Add a union ldlm_policy_data * parameter to
md_enqueue(). Remove the unused function lmv_enqueue_remote().
