ia64/PCI: Fix incorrect PCI resource end address
commit f976721e826e ("ia64/PCI: Use ioremap() instead of open-coded
equivalent") introduced the following compiler warning,
arch/ia64/sn/kernel/io_init.c: In function 'sn_io_slot_fixup':
arch/ia64/sn/kernel/io_init.c:189:19: warning: 'addr' may be used uninitialized in this function [-Wmaybe-uninitialized]
res->end = addr + size;
^
'addr' is indeed uninitialised and the correct value to use is
res->start.
