Remove VERBOSE code in bacio.c

[edwardhartnett]

bacio.c has some code like this:

    /* Check for illegal combinations of options */
    if (( BAOPEN_RONLY & *mode) &&
        ( (BAOPEN_WONLY & *mode) || (BAOPEN_WONLY_TRUNC & *mode) || (BAOPEN_WONLY_APPEND & *mode) ) ) {
#ifdef VERBOSE
        printf("illegal -- trying to open both read only and write only\n");
#endif
        return 255;
    }

Note the VERBOSE pre-processor. It is never set so the verbose code is never run.

These kind of verbose statements are not that helpful, and are not available to the end user. They should be removed to unclutter the code.
