NAME
   VShdfsize - computes the byte size of the field(s) of a vdata.

DESCRIPTION
   The size is the byte size of the fields of a vdata in a hdf file.
   This routine is very similar to the HDF API routine VSsizeof except
   it uses (struct vdata_desc).wlist.isize to compute the field size
   instead of (struct vdata_desc).wlist.esize as VSsizeof.

RETURNS
   The byte size of the field(s), positive integer, on success; 
   otherwise, returns FAIL.
