cxl: Add cookie parameter to afu_release_irqs()

Browse Source 
Add cookie parameter to afu_release_irqs() so that we can pass in a different
cookie than the context structure.  This will be useful for other kernel
drivers that want to call this but get their own cookie back in the interrupt
handler.

Update all existing call sites.
