CVE-2023-52902

In the Linux kernel, the following vulnerability has been resolved: nommu: fix memory leak in do_mmap() error path The preallocation of the maple tree nodes may leak if the error path to "error_just_free" is taken. Fix this by moving the freeing of the maple tree nodes to a shared location for all error paths.
