NFC: nci: Add some bounds checking in nci_hci_cmd_received()
This is similar to commit 674d9de0 ("NFC: Fix possible memory corruption when handling SHDLC I-Frame commands"). I'm not totally sure, but I think that commit description may have overstated the danger. I was under the impression that this data came from the firmware? If you can't trust your networking firmware, then you're already in trouble. Anyway, these days we add bounds checking where ever we can and we call it kernel hardening. Better safe than sorry.
