Juergen Gross 0891fb39ba xen/events: don't use chip_data for legacy IRQs 
Since commit c330fb1ddc ("XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.")
Xen is using the chip_data pointer for storing IRQ specific data. When
running as a HVM domain this can result in problems for legacy IRQs, as
those might use chip_data for their own purposes.

Use a local array for this purpose in case of legacy IRQs, avoiding the
double use.

Fixes: c330fb1ddc ("XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.")
