mesh: Use ieee80211w profile parameter

This is initial step in fixing issues in how PMF configuration for RSN
mesh was handled. PMF is an optional capability for mesh and it needs to
be configured consistently in both hostapd structures (to get proper
RSNE) and key configuration (not included in this commit).
