btrfs: use a runtime flag to indicate an inode is a free space inode

We always check the root of an inode as well as it's inode number to
determine if it's a free space inode.  This is problematic as the helper
is in a header file where it doesn't have the fs_info definition.  To
avoid this and make the check a little cleaner simply add a flag to the
runtime_flags to indicate that the inode is a free space inode, set that
when we create the inode, and then change the helper to check for this
flag.
