net: phy: mscc: macsec: clear encryption keys when freeing a flow
Commitaaab73f8fb
("macsec: clear encryption keys from the stack after setting up offload") made sure to clean encryption keys from the stack after setting up offloading, but the MSCC PHY driver made a copy, kept it in the flow data and did not clear it when freeing a flow. Fix this. Fixes:28c5107aa9
