wifi: iwlwifi: mvm: simplify the uAPSD coexistence limitation code

uAPSD can't be enabled on BSS or P2P Client if there is
another active interface (e.g. associated client). Allow
the code that apply those limitations to run on BSS as well.
Also forbid uAPSD if we have an IBSS or NAN interface in
the system.
Since we are now forbidding uAPSD in any concurrency
scenario, we don't need to check the number of PHY
contexts.
