[IA64] kexec/kdump: call xen_machine_kexec_setup_resources after init_bootmem

Early on in find_memory(), reserve_memory() is called,
which in turn calls xen_machine_kexec_setup_resources()
and in turn alloc_bootmem_low().

However, before alloc_bootmem_low() can be called,
init_bootmem() needs to be called.

To resolve this problem, the call to xen_machine_kexec_setup_resources()
is moved to just after the call to init_bootmem() in alloc_bootmem_low().
