data_smart.py: make use of expand cache in getVar() 

Currently if passing expand=True to getVar() function, it will pass the
handling to getVarFlag(), which doesn't get any benefit from the expand
cache.

Call the expand() function separately in getVar() to make use of the
expand cache, which can decrease the parsing time by 40%.
(from current 49s to 27s)
