Fix crash in PDB when loading corrupt file.
There are probably hundreds of crashers we can find by fuzzing
more. For now we do the simplest possible validation of the
block size. Later, more complicated validations can verify that
other fields of the super block such as directory size, number
of blocks, agree with the size of the file etc.
