Fix the bug in the verdict description for ComplexOptCheck

Before the fix:
CONFIG_EFI_DISABLE_PCI_DMA | kconfig | y | clipos | self_protection | OK: not found

After the fix:
CONFIG_EFI_DISABLE_PCI_DMA | kconfig | y | clipos | self_protection | OK: CONFIG_EFI not found

Also added the assertions preventing similar bugs in future.
