maple_tree: Fix overrunning end of node into RETRY entries.

When entries are moved and replaced with a RETRY, the node will end
prior to hitting a 0 pivot or the end of the node.  Fix this scenario by
detecting the pivot > mas->max and handle these cases correctly.

This also fixes the validation code to avoid checking the range on RETRY
entries.
