[PATCH] Hostapd does not update WPS credentials on SIGHUP

[Dmitry Koroban <dkoroban@xxxxxxxxxxxx>]

Faced this issue on v2.6, but 2.10 seems to have it too.
Steps to reproduce:
1. Start hostapd with WPS enabled
2. Change passphrase in hostapd.conf
3. Send SIGHUP to hostapd
4. Try to connect client using wps_pbc
5. Client receives old passphrase and cannot connect
