Laszlo Ersek 7602900aba ArmVirtualizationPkg: PlatformIntelBdsLib: lack of QEMU kernel is no error
When the user doesn't pass a kernel with QEMU's "-kernel" switch, the
firmware sees a zero-sized kernel blob via the QemuFwCfgItemKernelSize
key; there's no way to distinguish "no kernel" from "zero sized kernel".
In both cases TryRunningQemuKernel() proceeds as far as gBS->LoadImage(),
which then rejects the zero sized synthetic file with EFI_UNSUPPORTED.

This is known and works fully as expected; however we should rather catch
the much more frequent "no kernel" case earlier, in order to avoid the
EFI_D_ERROR message

  TryRunningQemuKernel: LoadImage(): Unsupported

which is arguably meaningless noise for the "no kernel" case.
