Jan Kara c1ad35dd05 udf: Avoid using stale lengthOfImpUse 
udf_write_fi() uses lengthOfImpUse of the entry it is writing to.
However this field has not yet been initialized so it either contains
completely bogus value or value from last directory entry at that place.
In either case this is wrong and can lead to filesystem corruption or
kernel crashes.
