We can detect that a FW SYSASSERT is due to missing PNVM data by checking the assertion code. When this happens, it's is useful for the user if we print the filename where the driver is looking for the data. Add the PNVM missing assertion code to the dump list and print out the name of the file we're looking for when this happens.
