qcacmn: Fix GTK offload req params

Currently the host sends the fixed gtk offload params
and the FILS TLV params, even when the FILS feature is disabled
in the host, which force firmware to pick the KEK from the
FILS TLV structure rather than from the fixed param structure,
which further leads to GTK re-keying feature fail.

Fix is to send only the fixed params in case when host doesnt
supports FILS.
