net: Revert recent Spectre-v1 patches.
This reverts:
50d5258634ae ("net: core: Fix Spectre v1 vulnerability")
d686026b1e6e ("phonet: af_phonet: Fix Spectre v1 vulnerability")
a95386f0390a ("nfc: af_nfc: Fix Spectre v1 vulnerability")
a3ac5817ffe8 ("can: af_can: Fix Spectre v1 vulnerability")
After some discussion with Alexei Starovoitov these all seem to
be completely unnecessary.
