gkodinov/kgeorge@macbook.gmz 20d94f1105 Bug #25382: Passing NULL to an UDF called from stored procedures ...

crashes server
 Check for null value is reliable only after calling some of the 
 val_xxx() methods. If the val_xxx() method is not called
 the null_value flag will be set only for certain types of NULL
 values (like SQL constant NULLs for example).
 This caused a crash while trying to dereference a NULL pointer
 that is returned by val_str() for NULL values.
 Fixed by swapping the order of val_xxx() and null_value check.
