macsec: delete new rxsc when offload fails
Currently we get an inconsistent state:
- netlink returns the error to userspace
- the RXSC is installed but not offloaded
Then the device could get confused when we try to add an RXSA, because
the RXSC isn't supposed to exist.
Fixes: 3cf3227a21d1 ("net: macsec: hardware offloading infrastructure")
