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()
function, to allow btrfs_print_leaf() functions to be called in gdb or
to debug temporary btrfs in make_btrfs() without a valid root.
