For better error reporting to user space, add extack messages when gact
action offload fails.
Example:
# echo 1 > /sys/kernel/tracing/events/netlink/netlink_extack/enable
# tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action continue
Error: cls_matchall: Failed to setup flow action.
We have an error talking to the kernel
# cat /sys/kernel/tracing/trace_pipe
tc-181 [002] b..1. 105.493450: netlink_extack: msg=act_gact: Offload of "continue" action is not supported
tc-181 [002] ..... 105.493466: netlink_extack: msg=cls_matchall: Failed to setup flow action
# tc filter add dev dummy0 ingress pref 1 proto all matchall skip_sw action reclassify
Error: cls_matchall: Failed to setup flow action.
We have an error talking to the kernel

tc-183 [002] b..1. 124.126477: netlink_extack: msg=act_gact: Offload of "reclassify" action is not supported
