powerpc/kdump: Fix powernv build break when KEXEC_CORE=n
If KEXEC_CORE is not enabled, powernv builds fail as follows.
arch/powerpc/platforms/powernv/smp.c: In function 'pnv_smp_cpu_kill_self':
arch/powerpc/platforms/powernv/smp.c:236:4: error:
implicit declaration of function 'crash_ipi_callback'
Add dummy function calls, similar to kdump_in_progress(), to solve the
problem.
Fixes: 4145f358644b ("powernv/kdump: Fix cases where the kdump kernel can get HMI's")
