e2fsck: inspect inline dir data as two directory blocks

The design of inline directories (apparently) calls for the i_block[]
region and the EA regions to be treated as if they were two separate
blocks of dirents.  Effectively this means that it is impossible for a
directory entry to straddle both areas.  e2fsck doesn't enforce this,
so teach it to do so.  e2fslib already knows to do this....
