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.
