Subject: [PATCH] hostapd: Update the hostapd module to handle the NULL value
 of wds_bridge.

By default, the wds_bridge parameter in the hostapd config file
is NULL character,So it updates the NULL character as bridge name.
Because of this, it fails to add the wds interface into the
bridge while running the  hostapd manually.


Earlier the bridge value assigns at the hostapd_set_wds_sta module,
So it does not cause any issue while reading the value from hostapd
config. Here the wds_bridge parameter is updated while asigning the
bridge name at hostapd_config_fill module.Then again it re-assign
the value of wds_bridge parameter. At this time wds_bridge
parameter is filled with null character as in hostapd config file,
then it is considered as a valid pointer and re-update the wds_bridge
variable.


This change checks the wds_bridge parameter and assign
the wds bridge name as per in the hostapd config, when the
character is not  NULL. Otherwise, the wds_bridge remains
in the default bridge interface name.
