Jeremy Cline 67f0f20e33 nfc: nci: assert requested protocol is valid
[ Upstream commit 354a6e707e29cb0c007176ee5b8db8be7bd2dee0 ]

The protocol is used in a bit mask to determine if the protocol is
supported. Assert the provided protocol is less than the maximum
defined so it doesn't potentially perform a shift-out-of-bounds and
provide a clearer error for undefined protocols vs unsupported ones.

Fixes: 6a2968aaf50c ("NFC: basic NCI protocol implementation")
