maple_tree: make maple state reusable after mas_empty_area_rev()

Browse source

commit fad8e4291d 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.
