Bug Description

fwts don't do anything when uefidump parser device path for End of Hardware Device Path - End This Instance of a Device Path sub-type(sub-type 0x01). It causes that the device path be show without knowing the "End This Instance of a Device Path sub-type" is included.
For example,
  Device Path: \ACPI(0xa0341d0,0x0)\PCI(0x0,0x2)\ACPI_ADR(0x80010302)\ACPI(0xa0341d0,0x0)\PCI(0x0,0x1f)\ACPI(0x50141d0,0x0)\UART(115200,8,1,1)\VENDOR(11d2f9be-0c9a-9000-27-3f-c1-4d-7f-01-04-00)\ACPI(0xa0341d0,0x0)\PCI(0x0,0x2)\ACPI_ADR(0x80010100).

According to the UEFI spec section 9.3.1 the "End This Instance of a Device Path sub-type",
Sub-Type 0x01 – End This Instance of a Device Path and start a new Device Path
It should be improved to show the new Device path start.

For example,
  Device Path: \ACPI(0xa0341d0,0x0)\PCI(0x0,0x2)\ACPI_ADR(0x80010302)
  Device Path: \ACPI(0xa0341d0,0x0)\PCI(0x0,0x1f)\ACPI(0x50141d0,0x0)\UART(115200,8,1,1)\VENDOR(11d2f9be-0c9a-9000-27-3f-c1-4d-7f-01-04-00)
  Device Path: \ACPI(0xa0341d0,0x0)\PCI(0x0,0x2)\ACPI_ADR(0x80010100).
