Fixed 'warning 208' (all my fault)

Is all my fault (i'm so terribly sorry) for bringing this 'warning 208: function with tag result used before definition, forcing reparse' for these functions:
- bool:db_set_row_index
- bool:db_free_result_hook
- bool:db_set_synchronous
to fix this you need to delete the tag ('bool:')

CAN YOU EXPLAIN WHY THIS IS HAPPENING, I DON'T SEE THE ISSUE FOR USING THE TAG BUT PAWNO HAS ANOTHER OPINION.
