smb: move create_durable_handle_reconnect_v2 to common/smb2pdu.h

Modify the following places:

  - some fields in "struct create_durable_reconn_v2_req" ->
                        struct durable_reconnect_context_v2
  - create_durable_reconn_v2_req -> create_durable_handle_reconnect_v2

Then move duplicate definitions to common header file.
