leaudio: Fix choosing available configuration

When devices of the group are known, configuration are chosen for all
the available context types based on the capabilities of the remote
devices.
Later during configuration, code is choosing best CIG parameters
looking into remote capabilities and also by determining topology
(strategy).
This patch, adds strategy check when configuration is chosen for the
available context, so we are sure that the same configuration is
chosen later when CIG is created.
