Cupertino Miranda 41d047a871 bpf/verifier: relax MUL range computation check 
MUL instruction required that src_reg would be a known value (i.e.
src_reg would be a const value). The condition in this case can be
relaxed, since the range computation algorithm used in current code
already supports a proper range computation for any valid range value on
its operands.
