[PATCH v2 15/35] nfc: st-nci: Keep st_nci_gates unchanged in load_session

[Christophe Ricard <christophe.ricard-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

We need to keep initial st_nci_gates values in order for
nci_hci_dev_connect_gates to create and open pipe when necessary.

For example after a firmware update CLF pipes are cleared. Changing pipe
values in st_nci_gates was causing nci_hci_dev_connect_gates not using
accurate pipes value.
