c/r: prctl: less paranoid prctl_set_mm_exe_file()
"no other files mapped" requirement from my previous patch (c/r: prctl:
update prctl_set_mm_exe_file() after mm->num_exe_file_vmas removal) is too
paranoid, it forbids operation even if there mapped one shared-anon vma.
Let's check that current mm->exe_file already unmapped, in this case
exe_file symlink already outdated and its changing is reasonable.
Plus, this patch fixes exit code in case operation success.
