[xen-devel][PATCH][VTD] Fix apic pin to interrupt remapping table index

["Han, Weidong" <weidong.han@xxxxxxxxx>]

Originally, it calls xmalloc to set index in ioapic_rte_to_remap_entry(). When 
make with debug=y, it may trigger spinlock BUG_ON because allocate memory with 
interrupt disabled.

This patch doesn't allocate list_head entry in ioapic_rte_to_remap_entry(), 
instead allocate the array in enable_intremap() to avoid allocating memory with 
interrupt disabled.
