The early loader just ends its microcode container file processing when it
is unable to parse some patch section, but keeps the already read patches
from this file for their eventual application.
We can do the same in the late loader - we'll just return an error if we
are unable to parse any patches.
Note that we already do silently skip patches in the late loader for
smaller issues like lack of an equivalence table entry, family-size
mismatch or an unsupported chipset match type.
