cbfs: change 1 message level to WARNING if cbfs can't find specific data

In some cases, we need to use 1 common VGA device ID to share
among different VGA devices.
But it will show error when it can't find a specific pci rom
by PCI DID.
in fact, it will find the pci rom with common vga ID.
Without this commit, you may need to skip error check during
suspend_stress_test

Without this patch, power_Resume test will fail.
