QSYS2.USER_INFO and USER_INFO_BASIC view change

With IBM i 7.5, there is a change to the MAXIMUM_ALLOWED_STORAGE (MAXSTGLRG) column within the QSYS2.USER_INFO view and the QSYS2.USER_INFO_BASIC view. In prior releases, if there was no maximum amount of allowed storage for the user, the column contained the value 9,223,372,036,854,775,807 (Hex 7FFFFFFFFFFFFFFF) instead of the documented value of null. IBM i 7.5 will correctly return a null for this column when there is no maximum set.
