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.
