net: phy: mscc: macsec: clear encryption keys when freeing a flow

Browse source 
Commit aaab73f8fb ("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.
