WPS: Fix segmentation fault in new DH key derivation
Commit 4104267e81b0a0acdb43f693a67f236b3237a719 ('Fix memory leak on NFC DH generation error path') modified dh5_init() behavior in the non-OpenSSL implementation to free the public key (if any was previously set). However, this did not update one of the callers to make sure the publ argument in the call is initialized. This could result in trying to free invalid pointer and segmentation fault when hostapd or wpa_supplicant was built against some other crypto library than OpenSSL.
