executor: x86: factor out common code in rdmsr()/wrmsr()
While at it, fix a bug in rdmsr() that apparently lost the top 32 bits.
Also fix a bug in Intel's Secondary Processor-based Controls:
we were incorrectly using the top 32 bits of
X86_MSR_IA32_VMX_PROCBASED_CTLS2 to enable all the available controls
without additional setup. This only worked because rdmsr() zeroed out
those top bits.
