1. UCP/AM: Fix request datatype state during CM switch …

   When switching between transports, we can add new memry registration
   handles to req->send.state.dt by calling ucp_send_request_add_reg_lane()
   from ucp_do_am_zcopy_single(). Should not save 'state' before calling
   add_reg_lane() - otherwise the new memory registration will be
   overridden.
   
   This fixes failure on r-vmb-ppc-jenkins in test_ucp_sockaddr_cm_switch
   test with the symptom "Error: Input/output error". It is actually a
   local protection error (PD violation) due to using wrong uct_mem_h.
