udf: Reject read requests with an invalid length

- If the size is negative or if rounding it up to a multiple of
  the block size overflows, fail the read request with ERANGE.

- While here, add a sanity check that the ICB length for the root
  directory is at least as long as a minimum-sized file entry.
