OvmfPkg/QemuFlashFvbServicesRuntimeDxe: Fix erase blocks for SEV-ES

Browse Source 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3008

The original SEV-ES support missed updating the QemuFlashEraseBlock()
function to successfully erase blocks. Update QemuFlashEraseBlock() to
call the QemuFlashPtrWrite() to be able to successfully perform the
commands under SEV-ES.
