x86: Fix NULL pointer access in irq_force_complete_move() for Xen guests
commit bbd391a15d82e14efe9d69ba64cadb855b061dba upstream.
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.
