[svn-r16803] Purpose: Fix bug 1548

Description:
When writing data to a dataset, the data transform was performed after type conversion.
This caused an error if the file type was non-native.  This has been changed so data
transforms are always performed on the memory type.

Tested: jam, linew. smirom (h5committest)
