[PATCH] Do not proceed when get_num_dumpable_cyclic() fails
Currently, when get_num_dumpable_cyclic() fails and returns FALSE in
create_dump_bitmap(), info->num_dumpable is set to 0 and makedumpfile
proceeds to write a broken dumpfile slowly with incorrect progress
indicator due to the value.
It should not proceed when get_num_dumpable_cyclic() fails.
