Subject: [PATCH v2] wilc1000: use wilc handler as cookie in request_threaded_irq()

From: Ajay Singh <[email protected]>

Use same cookie for request_threaded_irq() & free_irq() to properly free
IRQ during module unload. free_irq() already uses *wilc* handler so the
changes are required for request_threaded_irq().
