Save last NFCEE command separately

When receiving NCI notification for NFCEE commands, the handle value is
retrieved from nfc_cd.last_cmd.
If another NCI command (not NFCEE) is sent between the last
NFCEE command and its corresponding notification, this value is lost.
Adding a dedicated field to save the last NFCEE command will prevent it.
