mm/mmap.c: rb_parent is not necessary in __vma_link_list()

Now we use rb_parent to get next, while this is not necessary.

When prev is NULL, this means vma should be the first element in the list.

mm/mmap.c: rb_parent is not necessary in __vma_link_list()

Now we use rb_parent to get next, while this is not necessary.

When prev is NULL, this means vma should be the first element in the list.
Then next should be current first one (mm->mmap), no matter whether we
have parent or not.

After removing it, the code shows the beauty of symmetry.

====================
pull-request: bpf-next 2019-11-26

The following pull-request contains BPF updates for your *net-next* tree.

We've added 2 non-merge commits during the last 1 day(s) which contain
a total of 2 files changed, 14 insertions(+), 3 deletions(-).

The main changes, 2 small fixes are:

1) Fix libbpf out of tree compilation which complained about unknown u32
type used in libbpf_find_vmlinux_btf_id() which needs to be __u32 instead,
from Andrii Nakryiko.

2) Follow-up fix for the prior BPF mmap series where kbuild bot complained
about missing vmalloc_user_node_flags() for no-MMU, also from Andrii Nakryiko.
