fs: remove vfs_follow_link

Browse Source 
For a long time no filesystem has been using vfs_follow_link, and as seen
by recent filesystem submissions any new use is accidental as well.

Remove vfs_follow_link, document the replacement in
Documentation/filesystems/porting and also rename __vfs_follow_link
to match its only caller better.

->readdir() is gone now; switch to ->iterate()
[mandatory]
vfs_follow_link has been removed. Filesystems must use nd_set_link
from ->follow_link for normal symlinks, or nd_jump_link for magic
/proc/<pid> style links.
