KVM: VMX: Drop obsolete branch hint prefixes from inline asm
Remove explicit branch hint prefixes (.byte 0x2e / 0x3e) from VMX
inline assembly sequences.
These prefixes (CS/DS segment overrides used as branch hints on
very old x86 CPUs) have been ignored by modern processors for a
long time. Keeping them provides no measurable benefit and only
enlarges the generated code.
No functional change intended.
