OWE: Do not try to enable PMF for non-RSN associations

Browse Source 
Explicitly set the PMF configuration to 0 (NO_MGMT_FRAME_PROTECTION) for
non-RSN associations. This specifically helps with OWE transition mode
when the network block is configured with PMF set to required, but the
BSS selected is in open mode. There is no point to try to enable PMF for
such an association.

This fixes issues with drivers that use the NL80211_ATTR_USE_MFP
attribute to set expectations for PMF use. The combination of non-RSN
connection with claimed requirement for PMF (NL80211_MFP_REQUIRED) could
cause such drivers to reject the connection in OWE transition mode.
