btrfs: if we're restriping, use the target restripe profile
Previously we depended on some weird behavior in our chunk allocator to
force the allocation of new stripes, so by the time we got to doing the
reduce we would usually already have a chunk with the proper target.
However that behavior causes other problems and needs to be removed.
First however we need to remove this check to only restripe if we
already have those available profiles, because if we're allocating our
first chunk it obviously will not be available. Simply use the target
as specified, and if that fails it'll be because we're out of space.
