OvmfPkg: QemuVideoDxe: eliminate useless Private->HardwareNeedsStarting
Currently, QemuVideoGraphicsOutputQueryMode() reports EFI_NOT_STARTED when
this boolean field is set.
However, QemuVideoGraphicsOutputQueryMode() is only available to callers
after the GOP interface has been installed. That in turn implies that the
following partial call tree has succeeded without errors:
QemuVideoControllerDriverStart()
QemuVideoGraphicsOutputConstructor()
QemuVideoGraphicsOutputSetMode(... 0 ...)
HardwareNeedsStarting = FALSE
InstallMultipleProtocolInterfaces(... GOP ...)
That is, when QemuVideoGraphicsOutputQueryMode() is reached,
HardwareNeedsStarting is always FALSE.
