btrfs-progs: Allow btrfs_leaf_free_space to accept NULL root
Btrfs_leaf_free_space() function is used to determine the leaf/node
size.
It's OK to use root->nodesize to determine nodesize, but in fact,
extent_buffer->len can also be used to determine the nodesize if caller
can ensure it's a tree block.
So this patch will add support for NULL root for btrfs_leaf_free_space()

Btrfs-progs: Do not force mixed block group creation unless '-M' option is specified
When creating small Btrfs filesystem instances (i.e. filesystem size <= 1GiB),
mkfs.btrfs fails if both sectorsize and nodesize are specified on the command
line and sectorsize != nodesize, since mixed block groups involves both data
and metadata blocks sharing the same block group. This is an incorrect behavior
when '-M' option isn't specified on the command line.
This commit makes optional the creation of mixed block groups i.e. Mixed block
groups are created only when -M option is specified on the command line.
Since we now allow small filesystem instances with sectorsize != nodesize to
be created, we can end up in the following situation,
[root@localhost ~]# mkfs.btrfs -f -n 65536 /dev/loop0

The ENOSPC occurs during the creation of the UUID tree. This is because of
things like large metadata block size, DUP mode used for metadata and global
reservation consuming space. Also, large nodesize does not make sense on small
filesystems, hence this should not be an issue.
