[PATCH v2 1/3] ShellPkg/HttpDynamicCommand: Fix possible uninitialized use

["Sergei Dmitrouk" <sergei@posteo.net>]

`Status` can be used uninitialized:

    /* Evaluates to FALSE */
    if (ShellGetExecutionBreakFlag ()) {
        Status = EFI_ABORTED;
        break;
    }

    /* Evaluates to FALSE */
    if (!Context->ContentDownloaded && !Context->ResponseToken.Event) {
        Status = ...;
        ASSERT_EFI_ERROR (Status);
    } else {
        ResponseMessage.Data.Response = NULL;
    }

    /* UNINITIALIZED USE */
    if (EFI_ERROR (Status)) {
        break;
    }
