selftests/statmount: Fix file descriptor leak in setup_namespace

Browse source

In setup_namespace(), f_mountinfo is opened with fopen() at line 115
but is never closed. Multiple ksft_exit_fail_msg() calls exit the
program without closing this file descriptor, and the cleanup_namespace()
function registered with atexit() also doesn't close it.

Add fclose(f_mountinfo) in cleanup_namespace() to ensure the file
descriptor is properly closed on both normal and error exit paths,
since cleanup_namespace() is already registered as an atexit handler.
