mas_extend_spanning_null() was not modifying the range min and range max
of the resulting store operation.  The result was that the maple write
state no longer matched what the write was doing.  This was not an issue
as the values were previously not used, but to make the ma_wr_state usable
in future changes, the range min/max stored in the ma_wr_state for left
and right need to be consistent with the operation.
