riscv, bpf: use lw when reading int cpu in BPF_MOV64_PERCPU_REG
emit_ld is wrong, because thread_info.cpu is 32-bit, not xlen-bit wide.
The struct currently has a hole after cpu, so little endian accesses
seemed fine.
Fixes: 19c56d4e5be1 ("riscv, bpf: add internal-only MOV instruction to resolve per-CPU addrs")
