Prarit Bhargava bbd391a15d x86: Fix NULL pointer access in irq_force_complete_move() for Xen guests 
Upstream PV guests fail to boot because of a NULL pointer in
irq_force_complete_move().  It is possible that xen guests have
irq_desc->chip_data = NULL.

Test for NULL chip_data pointer before attempting to complete an irq move.
