net: pse-pd: Rectify and adapt the naming of admin_cotrol member of struct pse_control_config

In commit 18ff0bcd ("ethtool: add interface to interact with Ethernet
Power Equipment"), the 'pse_control_config' structure was introduced,
housing a single member labeled 'admin_cotrol' responsible for maintaining
the operational state of the PoDL PSE functions.

A noticeable typographical error exists in the naming of this field
('cotrol' should be corrected to 'control'), which this commit aims to
rectify.

Furthermore, with upcoming extensions of this structure to encompass PoE
functionalities, the field is being renamed to 'podl_admin_state' to
distinctly indicate that this state is tailored specifically for PoDL."
