[PATCH] Use return value of count_dyn_reconf_memory_ranges()

[Bernhard Walle]

This patch fixes the build error

    kexec/arch/ppc64/kexec-ppc64.c:140: \
        warning: control reaches end of non-void function

The patch returns 0 on success, and checks when the function is called
for a non-zero value.
