nVMX x86: check posted-interrupt descriptor addresss on vmentry of L2
According to section "Checks on VMX Controls" in Intel SDM vol 3C,
the following check needs to be enforced on vmentry of L2 guests:
- Bits 5:0 of the posted-interrupt descriptor address are all 0.
- The posted-interrupt descriptor address does not set any bits
beyond the processor's physical-address width.
