Gregory Nutt 621151a523 Fix some macOS sim warnings.
These warnings fix a class of warnings that I saw during CI checks for macOS sim builds.  For example:

    devif/devif_callback.c:111:49: warning: for loop has empty body [-Wempty-body]
                   prev = curr, curr = curr->nxtdev);
                                                    ^
    devif/devif_callback.c:111:49: note: put the semicolon on a separate line to silence this warning

I did not put the semi-colon on a separate line, but used braces.
