[PATCH 5.0 084/101] kvm/x86: Move MSR_IA32_ARCH_CAPABILITIES to array emulated_msrs

[Greg Kroah-Hartman]

[ Upstream commit 2bdb76c015df7125783d8394d6339d181cb5bc30 ]

Since MSR_IA32_ARCH_CAPABILITIES is emualted unconditionally even if
host doesn't suppot it. We should move it to array emulated_msrs from
arry msrs_to_save, to report to userspace that guest support this msr.
