maple_tree: make maple state reusable after mas_empty_area_rev()
commit fad8e4291da5e3243e086622df63cb952db444d8 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.
