[PATCH] hostapd: output hw_mode when using STATUS

[Antonio Prcela]

Adding the hw_mode config parameter to the STATUS output to easier determine
the current hw_mode of an hostapd access-point. Currently neither STATUS,
GET hw_mode, nor GET_CONFIG output it.

Useful if the hostapd access point has been created with wpa_ctrl_request()
without using a *.conf file, like hostapd.conf.
