netfilter: nf_tables: add and use BE register load-store helpers

Same as the existing ones, no conversions. This is just for sparse sake
only so that we no longer mix be16/u16 and be32/u32 types.

Alternative is to add __force __beX in various places, but this
seems nicer.

objdiff shows no changes.
