backports: no longer support kernels < 3.10

Since CRYPTO_CMAC was introduced in 3.10, and mac80211
depends on it, we basically get nothing out of it anyway.

I'm not removing the support code (yet) since it actually
compiles, and perhaps somebody has a need for (certain)
kernel versions lower than 3.10.
