net: sched: flower: only return error from hw offload if skip_sw

Recently introduced tc_setup_flow_action() can fail when parsing tcf_exts
on some unsupported action commands. However, this should not affect the
case when user did not explicitly request hw offload by setting skip_sw
flag. Modify tc_setup_flow_action() callers to only propagate the error if
skip_sw flag is set for filter that is being offloaded, and set extack
error message in that case.
