backports: fix genetlink backport

On kernels that already have pre_doit/post_doit, we don't
fake them by re-assigning all ops and their doit, but then
we clearly need to copy the pointers. Fix that oversight.

backports: add current_user_ns()

current_user_ns() is used by seq_user_ns() if CONFIG_USER_NS is set and
kernel version <= 2.6.38.
This was added to the kernel in version 2.6.29.
