Fix ndlp nodelist not empty wait timeout during driver unloading (CR 127052)

In lpfc_set_rrq_active the code allocates an RRQ while lock are held. The
driver either need to make this allocation ATOMIC or remove the allocation from
the lock. We choose to remove the locked version of lpfc_set_rrq_active since
there were no users of this function. Then rearrange the code so that the
allocation does not occur while the lock is held.
