orinoco: initialise priv->hw before assigning the interrupt
commit 229bd792be0bad245b78ed8f119952733a4752e5 upstream.
The interrupt handler takes a lock - but since commit bcad6e80f3f this
lock goes through an indirection specified in the hermes_t structure.
We must therefore initialise the structure before setting up the
interrupt handler.
Fix orinoco_cs and spectrum_cs
