RISC-V: Don't rely on positional structure initialization

Without this I get a bunch of warnings along the lines of

    arch/riscv/kernel/module.c:535:26: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init]
      535 |         [R_RISCV_32] = { apply_r_riscv_32_rela },

This just mades the member initializers explicit instead of positional.
I also aligned some of the table, but mostly just to make the batch
editing go faster.
