[PATCH net 01/19] can: vxcan: Kconfig: fix description stating no local echo provided

From: Alexander Hölzl <redacted>

The Kconfig description of the vxcan kernel module erroneously states the
the vxcan interface does not provide a local echo of sent can frames.
However this behavior changed in commit 259bdba27e32 ("vxcan: enable local
echo for sent CAN frames") and vxcan interfaces now provide a local echo.

Change the description of the vxcan module in the Kconfig to reflect this
change.
