Describe the problem you're observing

When dumping blockpointer with :b flag and using offset containing 0, for example, when dumping the first blockpointer in the indirect block with zdb -R cow 0:10007a00:20000L/400P:db0 zdb will print ***Invalid flag: 0 alongside with proper blockpointer description

Reproducible with any zdb -R with :b flag containing 0 in the offset
