-Subject: maple_tree: fix mas_empty_area_rev() lower bound validation
-
-mas_empty_area_rev() was not correctly validating the start of a gap
-against the lower limit.  This could lead to the range starting lower than
-the requested minimum.
-
-Fix the issue by better validating a gap once one is found.
-
-This commit also adds tests to the maple tree test suite for this issue
-and tests the mas_empty_area() function for similar bound checking.
