Driver failed to join AP with specific BSSID(eg. 00:00:00:00:00:03).
The reason is WDA_IS_NULL_MAC_ADDRESS only checks the first 4 bytes
of mac address, due to which AP's BSSID failed the check, hence WDA
returned the join failure.
Fix WDA_IS_NULL_MAC_ADDRESS to check all 6 bytes of mac address.

Some specific AP will send assoc reject if DUT set the bits of
Ext Cap IE which AP not advertise in beacon or probe response.
To avoid the IoT issue, clear the bits in Ext Cap IE if AP not
support.

Ext Cap IE is defined as fixed length in driver. But some
AP sends beacon or probe resp with variable length of
Ext Cap IE, then dot11f will decode it to invalid value.
To fix this, use variable length for Ext Cap IE.
