irqbalance: remove local patch for socket directory

Upstream has finally patched the UI communication socket
creation to happen only if the irqbalance UI is enabled.

As we do not use the irqbalance UI, we can remove
our local fix implemented by 4f0c847828.
(If you want to enable irqbalance UI, the fix is still needed.)
