Does this patch fix an issue that results in incorrect behavior? Are the
event messages really longer than 2048 bytes?

Wouldn't it be better to determine the buffer length once during
initialization and cache that information in struct bsd_driver_data to
avoid the extra sysctl calls? Or can this change dynamically during
wpa_supplicant/hostapd process runtime? Is the realloc() to smaller
buffer really of any help here? Isn't the buffer freed more or less
immediately?
