iwlwifi: mvm: disallow new TDLS stations when appropriate
HW/FW constraints dictate that TDLS should only be used when a single
phy ctx is active. We also support at most 4 TDLS peers. We don't
support TDLS on a P2P vif.
Unify and move a phy-ctx counting implementation from the power-mgmt code
in order to simplify implementation.
