efi_capsule_data() is called in each of the EFI tests to create and setup the files we need. However, it also recreates the spi.bin file that holds the SPI flash contents we rely on for the test validation. This leads to weird errors since reading from the flash returns 0, instead of the expected value if the file has been recreated. Always restart our sandbox instance if the files are recreated.
