Subject: RDMA/rxe: Make rxe_type_info static const
Patch-mainline: v5.16-rc1
Git-commit: 000b8490ecacb3ad5145314ca235c0a17d0187bf
References: jsc#SLE-19249

Make struct rxe_type_info static const and local to the only uses.  Moves
a bit of data to text.

$ size drivers/infiniband/sw/rxe/rxe_pool.o* (defconfig w/ infiniband swe)
