      x86/spec-ctrl: Fix BTC/SRSO mitigations
      
      We were looking for SCF_entry_ibpb in the wrong variable in the 
top-of-stack
      block, and xen_spec_ctrl won't have had bit 5 set because Xen doesn't
      understand SPEC_CTRL_RRSBA_DIS_U yet.
      
      This is XSA-455 / CVE-2024-31142.
