x86: Remove move_cleanup_count from irq_cfg
move_cleanup_count for each irq in irq_cfg is keeping track of the total number of cpus that need to free the corresponding vectors associated with the irq which has now been migrated to new destination. As long as this move_cleanup_count is non-zero (i.e., as long as we have n't freed the vector allocations on the old destinations) we were preventing the irq's further migration. This cleanup count is unnecessary and it is enough to not allow the irq migration till we send the cleanup vector to the previous irq destination, for which we already have irq_cfg's move_in_progress. All we need to make sure is that we free the vector at the old desintation but we don't need to wait till that gets freed.
