HS 2.0R2: Fix OSEN IE parsing for in cipher setup (CID 68132)

Browse source 
The OSEN code path hardcodes number of struct wpa_ie_data items.
However, it did not clear the full structure and some uninitialized
fields could have been used (e.g., ie.mgmt_group_cipher for a debug
print and ie.capabilities for checking MFPC). Fix this by clearing the
ie data before filling in the hardcoded OSEN values.
