staging: ks7010_sdio: fix memory leak

Memory allocated for netdev at line 854:
netdev = alloc_etherdev(sizeof(*priv));
is not being free'd before return, hence
there is a memory leak.

Fix this by freeing netdev before return.

- Update subject and commit changelog.
- Just directly free netdev. Thanks to Dan Carpenter for the feedback.
