Merge branch 'qed-error-codes'

Asbjørn Sloth Tønnesen says:

====================
net: qede: avoid overruling error codes

This series fixes the qede driver, so that
qede_parse_flow_attr() and it's subfunctions
doesn't get their error codes overruled
(ie. turning -EOPNOTSUPP into -EINVAL).

---
I have two more patches along the same lines,
but they are not yet causing any issues,
so I have them destined for net-next.
(those are for qede_flow_spec_validate_unused()
and qede_flow_parse_ports().)

After that I have a series for converting to
extack + the final one for validating control
flags.
