Radim Krčmář 8352fdfc04 riscv, bpf: use lw when reading int cpu in bpf_get_smp_processor_id 
commit 8a16586fa7 upstream.

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: 2ddec2c80b ("riscv, bpf: inline bpf_get_smp_processor_id()")
