[PATCH v3 22/35] nfc: st-nci: Add error messages when an unexpected HCI event occurs

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

Potentially an unexpected HCI event may occur because of a firmware bug.
It could be transparent for the user but at least log this.
