Subject: [PATCH net-next v2 12/14] net: qede: use faked extack in qede_flow_spec_to_rule()
Since qede_parse_flow_attr() now does error reporting
through extack, then give it a fake extack and extract the
error message afterwards if one was set.
The extracted error message is then passed on through
DP_NOTICE(), including messages that was earlier issued
with DP_INFO().
This fake extack approach is already used by
mlxsw_env_linecard_modules_power_mode_apply() in
drivers/net/ethernet/mellanox/mlxsw/core_env.c
Only compile tested.

Note:
Even through _msg is marked in include/linux/netlink.h as
"don't access directly, use NL_SET_ERR_MSG", then the comment
above NL_SET_ERR_MSG, seams to indicate that it should be fine
to access it directly if for reading, as is done other places.
I could also add a NL_GET_ERR_MSG but I would rather not do that
in this series.
