can: af_can: do not access proto_tab directly use rcu_access_pointer instead
"proto_tab" is a RCU protected array, when directly accessing the array,
sparse throws these warnings:
CHECK /srv/work/frogger/socketcan/linux/net/can/af_can.c
net/can/af_can.c:115:14: error: incompatible types in comparison expression (different address spaces)
net/can/af_can.c:795:17: error: incompatible types in comparison expression (different address spaces)
net/can/af_can.c:816:9: error: incompatible types in comparison expression (different address spaces)
This patch fixes the problem by using rcu_access_pointer() and
annotating "proto_tab" array as __rcu.
