Add safety net for informing the kernel after writing a DOS partition table.
There is an unidentified condition that prevents udevd calling the BLKRRPART ioctl after a partition table is written. It looks like either the kernel or udevd drops device change events if they are too closely spaced in time. So, in the case where we expect udevd to call BLKRRPART, check /proc/partitions to make sure it has done so. Arbitrarily try 5 times, 100ms apart, before giving up and informing the kernel ourselves.
