x86/bugs: Move cpu_bugs_smt_update() down

Commit 6449f5baf9c78a7a442d64f4a61378a21c5db113 upstream.

cpu_bugs_smt_update() uses global variables from different mitigations. For
SMT updates it can't currently use vmscape_mitigation that is defined after
it.

Since cpu_bugs_smt_update() depends on many other mitigations, move it
after all mitigations are defined. With that, it can use vmscape_mitigation
in a moment.

No functional change.
