OVMF can't guarantee that the ASSERT() doesn't happen. Misbehaving
EFI applications can trigger this. So log a warning instead and try
to continue.
Reproducer: Fetch windows 11 22H2 iso image, boot it in qemu with OVMF.
Traced to BootServices->Stall() being called with IPL=TPL_HIGH_LEVEL
and Interrupts /enabled/ while windows is booting.
