orinoco: initialise priv->hw before assigning the interrupt

Browse source 
The interrupt handler takes a lock - but since commit bcad6e80f3 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
