[PATCH] btrfs-progs: remove data extents from the free space tree

[Josef Bacik <josef@toxicpanda.com>]

Dave reported a failure of mkfs-test 009 with the free space tree
enabled by default.  This is because 009 pre-populates the file system
with a given directory, and for some reason our data allocation path
isn't the same as in the kernel.  Fix this by making sure when we
allocate a data extent we remove the space from the free space tree, and
with this our mkfs tests now pass.

Issue: #410
