commit 0ede61d8589cc2d93 [file: convert to SLAB_TYPESAFE_BY_RCU]
renames lookup_fd_rcu to lookup_fdget_rcu, so we need to
version adjust the fdtable wrapper accordingly.

Signed-off-by: Bruce Ashfield <bruce.ashfield at gmail.com>

Repeating the comment from patch 1 of this series:

Someone else may or may not already have this in flight,
but I didn't see anything on the list or in the git

I ran into this failure when working on the v6.7-rc
kernel as part of yocto project kernel updates.

Tweak as necessary, as I'm no expert in the right way
to version these sort of changes.
