Subject: [PATCH] Assembe: fix bug in force_array - it wasn't forcing properly.

Since 'best' was expanded to hold replacement devices, we might
need to go up to raid_disks*2 to find devices to force.

Also fix another place when considering replacement drives would
be wrong (the 'chosen' device should never be a replacement).
