mcoverlayfs 4.18: re-define ovl_readlink
...
Apparently /proc needs it; it's normally implemented using get_link if
readlink isn't implemented but proc's get_link crashes the kernel in
this case (because nameidata is only defined for open* paths)

zap_vma_ptes no longer returns an error code as of Linux's
27d036e33237e4 ("mm: Remove return value of zap_vma_ptes()"),
where they decided nobody is interested in it....
Just copy the check out of the function.

A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats
