[TRIVIAL] Fix bitwise or on boolean operands warning / error

[ximinez]

High Level Overview of Change

I compile rippled with -werr. Clang 14 generated the following error.

src/ripple/app/tx/impl/CreateOffer.cpp:731:13: error: use of bitwise '&' with boolean operands [-Werror,-Wbitwise-instead-of-logical]
        if (!takerAmount.in.native() & !takerAmount.out.native())
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
                                     &&
src/ripple/app/tx/impl/CreateOffer.cpp:731:13: note: cast one or both operands to int to silence this warning
1 error generated.

Context of Change

I updated to Ubuntu 22.04, which ships with clang 14. Building rippled on the new system failed because of this issue.

Type of Change

• [X ] Refactor (non-breaking change that only restructures code)
