Binbin Wu b4fb261b18 hv: fix bug in some embedded assembly code in vmx ...

The patch fixes the issue when SOS can't boot using HV release version.

In current code, the assembly code for "sgdt" & "sidt" is not right.
The operand is output, not input.

Also, current code use "rdmsr" instruction to read MSR_IA32_SYSENTER_CS,
which doesn't sepcify the clobbered registers it uses.
This patch uses API msr_read to read MSR_IA32_SYSENTER_CS.
