[PATCH] UefiCpuPkg/RegisterCpuFeaturesLib: Set CpuFeatureEntry initial value

[Jeff Fan <jeff.fan@intel.com>]

CpuFeatureEntry will be set before using it. But VS2012 build reported the build
warning "potentially uninitialized local variable 'CpuFeatureEntry' used".

This fix is to set CpuFeatureEntry initial value and add ASSERT check later.
