From: Geert Uytterhoeven <geert+renesas@glider.be>

The help text for the CAN_ISOTP config symbol uses the acronym "PDU".  However,
this acronym is not explained here, nor in Documentation/networking/can.rst.

Expand the acronym to make it easier for users to decide if they need to enable
the CAN_ISOTP option or not.
