[PATCH v3 RESEND] driver core: Keep the supplier fwnode consistent with the device

[Herve Codina]

The commit 3a2dbc510c43 ("driver core: fw_devlink: Don't purge child
fwnode's consumer links") introduces the possibility to use the
supplier's parent device instead of the supplier itself.
In that case the supplier fwnode used is not updated and is no more
consistent with the supplier device used.

Use the fwnode consistent with the supplier device when checking flags.

Changes v2 -> v3:
  Do not update the supplier handle in order to keep the original handle
  for debug traces.

Changes v1 -> v2:
  Remove sup_handle check and related pr_debug() call as sup_handle cannot be
  invalid if sup_dev is valid.
