xfs: check for obviously bad level values in the bmbt root commit b3bf607d58520ea8c0666aeb4be60dbb724cd3a2 upstream. We can't handle a bmbt that's taller than BTREE_MAXLEVELS, and there's no such thing as a zero-level bmbt (for that we have extents format), so if we see this, send back an error code.
