Move NULL check for driver private data (drv_priv)

Browse source 
In the hostapd_cleanup_driver() function, the NULL check for the driver
private data (drv_priv) is located within the CONFIG_IEEE80211BE feature
flag. As a result, on platforms where CONFIG_IEEE80211BE is not defined,
driver->hapd_deinit(drv_priv) is called with drv_priv set to NULL. This
leads to a null pointer exception in wpa_driver_nl80211_deinit().

To address this issue, move the NULL check for drv_priv outside the
CONFIG_IEEE80211BE build flag. This ensures that the check is performed
regardless of the value of CONFIG_IEEE80211BE, preventing the NULL
pointer exception.
