NFC: Fix LLCP related build failure

llcp_mac routines should be static and inlined or build will fail with NFC selected without LLCP.

This patch fixes:

LD [M] net/nfc/nfc.o

John, if you want to revert d646960f7986fefb460a2b062d5ccc8ccfeacc3a, I can send you an updated one with that fix included. Let me know what you'd prefer.
