Christoph Hellwig 8f4af4b8e1 btrfs: sink parameter len to btrfs_split_ordered_extent ...

btrfs_split_ordered_extent is only ever asked to split out the beginning
of an ordered_extent (i.e. post == 0).  Change it to only take a len to
split out, and switch it to allocate the new extent for the beginning,
as that helps with callers that want to keep a pointer to the
ordered_extent that it is stealing from.
