Subject: [PATCH 5/8] NFC: NCI: Don't call setup if previous NCI request failed

If the previous nci_request (NCI reset) failed the setup function
was being called anyway. It shouldn't be called if the reset failed.

The result of the setup function is taken into consideration. If it
fails the init should fail.
