Dan Carpenter a3aefbfe45 net: nfc: fix bounds checking bugs on "pipe"
This is similar to commit 674d9de02a ("NFC: Fix possible memory
corruption when handling SHDLC I-Frame commands") and commit d7ee81ad09
("NFC: nci: Add some bounds checking in nci_hci_cmd_received()") which
added range checks on "pipe".

The "pipe" variable comes skb->data[0] in nfc_hci_msg_rx_work().
It's in the 0-255 range.  We're using it as the array index into the
hdev->pipes[] array which has NFC_HCI_MAX_PIPES (128) members.

Fixes: 118278f20a ("NFC: hci: Add pipes table to reference them with a tuple {gate, host}")
