maple_tree: make maple state reusable after mas_empty_area_rev()

commit fad8e429 upstream.

Stop using maple state min/max for the range by passing through pointers
for those values.  This will allow the maple state to be reused without
resetting.

Also add some logic to fail out early on searching with invalid
arguments.
