    hostapd: fix EAP-PWD in experimental hostapd-radius server
    
    Without initializing pwd_group, it's set to 0, which is reserved value.
    When EAP-PWD is used in wpa_supplicant/eapol_test, next error is seen:
    EAP-PWD: Server EAP-pwd-ID proposal: group=0 random=1 prf=1 prep=0
    EAP-pwd: Unsupported or disabled proposal

    (cherry picked from commit 9d78b2f53c48ddbc2f978e3365af183c69a33c84)
