[PATCH next] vfs: initialize m_list to fix crash in mnt_set_mountpoint

Fix mnt_set_mountpoint() crash: new_mountpoint() must initialize m_list.

Reported-by: Felipe Balbi <redacted>
Signed-off-by: Hugh Dickins <hughd@google.com>

I assume that this is a fix for commit 89f7ca1af15b ("vfs: Keep a list
of mounts on a mount point") that is currently i the vfs tree.  I will
apply this patch as a fix up for the vfs tree in linux-next today.

Yes, that's it: thanks a lot, Stephen, that will help everybody.

I should acknowledge that Thierry Reding posted the same fix (a few
lines away) before mine, but I only came across his later in the day.
