Change handling for "--assemble --force" when two drives disappeared at once.
...
If two drives in a raid5 disappear at the same time, then "-Af"
will add them both in rather than just one and forcing the array
to 'clean'. This is slightly safer in some cases.

If an auto-assembly attempt failes because the array cannot be
opened or because the array has already been created, then we
get into an infinite loop.

- Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele
stacked arrays.
- Allow mdassemble, when run a second time, to mark all arrays as writable.
This is useful if they are started read-only as is best at boot-time.
