    Fix enum warning in ath_hal's ar9002
    
    This fixes a clang 19 warning:
    
        sys/dev/ath/ath_hal/ar9002/ar9285_btcoex.c:57:32: error: comparison of different enumeration types ('HAL_BOOL' and 'HAL_ANT_SETTING') [-Werror,-Wenum-compare]
           57 |             (AH5212(ah)->ah_diversity != HAL_ANT_VARIABLE)) {
              |              ~~~~~~~~~~~~~~~~~~~~~~~~ ^  ~~~~~~~~~~~~~~~~
    
    The `ah_diversity` field of `struct ath_hal_5212` is of type `HAL_BOOL`,
    not the enum type `HAL_ANT_SETTING`. In other code, `ah_diversity` is
    set to `AH_TRUE` whenever the related field `ah_antControl` is set to
    `HAL_ANT_VARIABLE`.
    
    It is not entirely clear to me what the intended statement is here: the
    test as it is written now compares the enum value 0 to `ah_diversity`,
    so in effect it enables the following block whenever `ah_diversity` is
    `AH_TRUE`. Write it like that, to avoid the compiler warning.
