btrfs: make shrink_delalloc take space_info as an arg

Browse Source 
Currently shrink_delalloc just looks up the metadata space info, but
this won't work if we're trying to reclaim space for data chunks.  We
get the right space_info we want passed into flush_space, so simply pass
that along to shrink_delalloc.
