[PATCH] staging: et131x: let the freeing of memory more reasonable in error path

[Dan Carpenter]

Come on...  :/

Don't randomly add a pointless kfree() to one error path when there are
four later error paths in this function that don't have a kfree().  It
just makes the code more difficult to understand for no reason.

And we're not going to add a comment to every single error path
either.
