can: af_can: can_rcv(): replace WARN_ONCE by pr_warn_once
commit 8cb68751c115d176ec851ca56ecfbb411568c9e8 upstream.
If an invalid CAN frame is received, from a driver or from a tun
interface, a Kernel warning is generated.
This patch replaces the WARN_ONCE by a simple pr_warn_once, so that a
kernel, bootet with panic_on_warn, does not panic. A printk seems to be
more appropriate here.
