qsap: Remove support for wifi_fst from QSAP APIs

wifi_fst.h is no longer part of /hardware/libhardware_legacy/ ,
therefore, compilation of libqsap_sdk would fail. Remove dependencies
for wifi_fst from QSAP.

Additionally, skip calling 'chown' after changing configuration
parameters as QSAP is not changing ownership.
