Fixed erroneous type casting in HDF4Dataset::AnyTypeToDouble().

r31400 changed C-style type casting into C++-styled ones but unfortunately
it made wrong pointer dereferencing in HDF4Dataset::AnyTypeToDouble() method
effectively breaking reading georeference data and some other metadata from
HDF4-EOS datasets. This should fix it.
