stmmac: intel: Fix kernel crash due to wrong error path

Browse source

Unfortunately sometimes ->probe() may fail. The commit b9663b7ca6
("net: stmmac: Enable SERDES power up/down sequence")
messed up with error handling and thus:

[   12.811311] ------------[ cut here ]------------
[   12.811993] kernel BUG at net/core/dev.c:9937!

Fix this by properly crafted error path.
