qcacmn: Fix policy manager utfw API to delete all connection

policy_mgr_decr_connection_count_utfw() API is using
policy_mgr_psoc_enable() API to reset policy manager table as well
as timer deinit but it does more than resetting the table which causes
a stablity issue. For example, policy_mgr_psoc_enable() API calls to
reinitialization connection_update_done_evt event which triggers
stability issue as it has been already initialized once.

Purpose of delete all connection option is, to reset the policy
manager table, to reset any timers which can be achieved by
calling policy_mgr_psoc_disable() followed by policy_mgr_psoc_enable()
