Updated DpdkDeviceList to use internal::DeviceListBase.

[Dimi1010]

Changes:

• PointerVector's front(), back() and at() changed to return T* even in const on the rationale that modifying the pointee does not modify the vector's contents (the pointer in the vector isn't modified).
• Updated DpdkDeviceList to use internal::DeviceListBase.
