X86/nVMX: Properly set spec_ctrl and pred_cmd before merging MSRs

X86/nVMX: Properly set spec_ctrl and pred_cmd before merging MSRs

commit 206587a9fb764d71f035dc7f6d3b6488f5d5b304 upstream.

These two variables should check whether SPEC_CTRL and PRED_CMD are
supposed to be passed through to L2 guests or not. While
msr_write_intercepted_l01 would return 'true' if it is not passed through.

So just invert the result of msr_write_intercepted_l01 to implement the
correct semantics.
