Make Assemble/Force work on raid6 with 2 missing devices.
...
Previously it onl worked when one missing device.
Also split the "force" update_super method into two and it
is really serving two functions.

Work around bug in --add handling for version-1 superblocks
...
In 2.6.17 (and prior), the dev_number is ignored when a device
is added to an active array. Rather the first free number is used.
So we work around this by making sure we use the first free
number for dev_number.

From: Luca Berra <bluca@vodka.it>
glibc 2.4 is pedantic on ignoring return values from fprintf, fwrite and
write, so now we check the rval and actually do something with it.
in the Grow.c case i only print a warning, since i don't think we can do
anything in case we fail invalidating those superblocks (is should never
happen, but then...)
