net: pse-pd: pd692x0: Fix power limit retrieval

Browse source 
Fix incorrect data offset read in the pd692x0_pi_get_pw_limit callback.
The issue was previously unnoticed as it was only used by the regulator
API and not thoroughly tested, since the PSE is mainly controlled via
ethtool.

The function became actively used by ethtool after commit 3e9dbfec49
("net: pse-pd: Split ethtool_get_status into multiple callbacks"),
which led to the discovery of this issue.

Fix it by using the correct data offset.

Fixes: a87e699c9d ("net: pse-pd: pd692x0: Enhance with new current limit and voltage read callbacks")
