ext4: create a new BH_Verified flag to avoid unnecessary metadata validation

Create a new BH_Verified flag to indicate that we've verified all the
data in a buffer_head for correctness.  This allows us to bypass
expensive verification steps when they are not necessary without
missing them when they are.
