The ice_find_netlist_node function was introduced in commit 8a3a565f
("ice: add admin commands to access cgu configuration"). Variations of this
function were reviewed concurrently on both intel-wired-lan[1][2], and
netdev [3][4]

The variant I posted had a few changes due to review feedback which were
never incorporated into the DPLL series:

* Replace the references to ancient and long removed ICE_SUCCESS and
  ICE_ERR_DOES_NOT_EXIST status codes in the function comment.

* Return -ENOENT instead of -ENOTBLK, as a more common way to indicate that
  an entry doesn't exist.

* Avoid the use of memset() and use simple static initialization for the
  cmd variable.

* Use FIELD_PREP to assign the node_type_ctx.

* Remove an unnecessary local variable to keep track of rec_node_handle,
  just pass the node_handle pointer directly into ice_aq_get_netlist_node.
