Star Zeng 34b162d078 UefiCpuPkg/CpuCommonFeaturesLib: Aesni.c uses BIT0 and BIT1 reversedly
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1621

According to Intel SDM as below, the BIT0 should be treated as
lock bit, and BIT1 should be treated as disable(1)/enable(0) bit.

"11b: AES instructions are not available until next
RESET.
Otherwise, AES instructions are available.
If the configuration is not 01b, AES
instructions can be mis-configured if a privileged agent
unintentionally writes 11b"
