target/i386: ignore ARCH_CAPABILITIES features in user mode emulation
ARCH_CAPABILITIES is only accessible through a read-only MSR, so it has no impact on any user-mode operation (user-mode cannot read the MSR). So do not bother printing warnings about it in user mode emulation. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
