Replace PTKSA cache inline stubs with wrapper function stubs

Browse source 
PTKSA cache API is included in libpasn.so used by external modules,
e.g., Wi-Fi Aware. To avoid dependency on CONFIG_PTKSA_CACHE define for
the external modules at compile time, remove PTKSA cache static inline
functions from the header file and add wrapper function stubs.
