Subject: maple_tree: move mas_wr_end_piv() below mas_wr_extend_null()
Date: Wed, 31 May 2023 22:16:02 -0400
Relocate it and call mas_wr_extend_null() from within mas_wr_end_piv().
Extending the NULL may affect the end pivot value so call
mas_wr_endtend_null() from within mas_wr_end_piv() to keep it all
together.
