netfilter: nf_tables: add and use BE register load-store helpers
[ Upstream commit 7278b3c1e4ebf6f9c4cda07600f19824857c81fe ]
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.
