[PATCH 2.6.30] Network Drop Monitor: Make use of consume_skb() in af_can.c

Since commit ead2ceb0ec9f85cff19c43b5cdb2f8a054484431 so called end-of-line
points for skb's should use consume_skb() to free the socket buffer.

In opposite to consume_skb() the function kfree_skb() is intended to be used
for unexpected skb drops e.g. in error conditions that now can trigger the
network drop monitor if enabled.

This patch moves the skb end-of-line point in af_can.c to use consume_skb().
