In preparation to putting Hyper-V specific test pages to a dedicated struct, move eVMCS load logic from load_vmcs(). Tests call load_vmcs() directly and the only one which needs 'enlightened' version is evmcs_test so there's not much gain in having this merged. Temporary pass both GPA and HVA to load_evmcs().
