can: vxcan: Kconfig: fix description stating no local echo provided

Browse Source 
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 259bdba27e ("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.

When one end receives the packet it appears on its pair and vice
versa. The vxcan can be used for cross namespace communication.
In opposite to vcan loopback devices the vxcan only forwards CAN
frames to its pair and does *not* provide a local echo of sent
CAN frames. To disable a potential echo in af_can.c the vxcan driver
announces IFF_ECHO in the interface flags. To have a clean start
in each namespace the CAN GW hop counter is set to zero.

This driver can also be built as a module. If so, the module
will be called vxcan.
