x86/bugs: Fix BHI handling of RRSBA
The ARCH_CAP_RRSBA check isn't correct: RRSBA may have already been
disabled by the Spectre v2 mitigation (or can otherwise be disabled by
the BHI mitigation itself if needed). In that case retpolines are fine.
Fixes: ec9404e40e8f ("x86/bhi: Add BHI mitigation knob")
