net: pse-pd: fix kernel-doc function name for pse_control_find_by_id()

The kernel-doc comment header incorrectly referenced the function
name pse_control_find_net_by_id() instead of the actual function name
pse_control_find_by_id(). Correct the function name in the documentation
to match the implementation.
