Dan Carpenter 322a57551d nfc: nci: Potential off by one in ->pipes[] array 
[ Upstream commit 6491d698396fd5da4941980a35ca7c162a672016 ]

This is similar to commit e285d5bfb7 ("NFC: Fix the number of pipes")
where we changed NFC_HCI_MAX_PIPES from 127 to 128.

As the comment next to the define explains, the pipe identifier is 7
bits long.  The highest possible pipe is 127, but the number of possible
pipes is 128.  As the code is now, then there is potential for an
out of bounds array access:

    net/nfc/nci/hci.c:297 nci_hci_cmd_received() warn: array off by one?
    'ndev->hci_dev->pipes[pipe]' '0-127 == 127'

Fixes: 11f54f2286 ("NFC: nci: Add HCI over NCI protocol support")
