Aaron Lewis c034f2aa86 KVM: VMX: Fix conditions for guest IA32_XSS support 
Volume 4 of the SDM says that IA32_XSS is supported
if CPUID(EAX=0DH,ECX=1):EAX.XSS[bit 3] is set, so only the
X86_FEATURE_XSAVES check is necessary (X86_FEATURE_XSAVES is the Linux
name for CPUID(EAX=0DH,ECX=1):EAX.XSS[bit 3]).

Fixes: 4d763b168e ("KVM: VMX: check CPUID before allowing read/write of IA32_XSS")
