net: phy: mscc: macsec: clear encryption keys when freeing a flow
Commit aaab73f8fba4 ("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: 28c5107aa904 ("net: phy: mscc: macsec support")
