can: Use WARN_ONCE() instead of BUG_ON() for sanity check in receive path
To ensure a proper handling of CAN frames transported in skbuffs some checks
need to be performed at receive time.
As stated by Michael Olbrich and Luotao Fu BUG_ON() might be to restrictive.
This is right as we can just drop the non conform skbuff and the Kernel can
continue working.
This patch replaces the BUG_ON() with a WARN_ONCE() so that the system remains
healthy but we made the problem visible (once).
