leak
Patch-mainline: v6.1-rc8
Git-commit: 194cc051e29ea1641d424126b8f28f9d31d5c655

Currently MACsec's add Rx SA flow steering (fs) rule routine
uses a spec object which is dynamically allocated and do
not free it upon leaving. The above led to a memory leak.
Fix by freeing dynamically allocated objects.
