[HVM][SVM] Check if SVM is disabled by the BIOS before enabling it.

Newer BIOS implementations will be able to disable the SVM feature,
although an additional test of an MSR (VMCR 0xC0010114 bit 4) is
necessary (set equals disabled). Bit 4 of MSR 0xc0010114 returns 0
(SVM enabled) on machines with older BIOS' without the SVM disable
feature support.
