bpf: Fix print_reg_state's constant scalar dump
print_reg_state() should not consider adding reg->off to reg->var_off.value
when dumping scalars. Scalars can be produced with reg->off != 0 through
BPF_ADD_CONST, and thus as-is this can skew the register log dump.
Fixes: 98d7ca374ba4 ("bpf: Track delta between "linked" registers.")
