qcacld-3.0: Remove check of hw mode from connect path

Currently the driver checks that whether DBS connection
is allowed in concurrency or not, and if it is not
allowed, MCC should happen.
But the check of policy_mgr_is_hwmode_set_for_given_chnl blocks
the connection in MCC, because it checks whether the DBS
mode is set or not, which should not be case always, for
example in MCC case scenarios, or SBS case scenarios in
future.
Lets take a case scenario to understand this :-
1. Keep the ini channel_select_logic_conc = 0
        this would disable the dbs for STA+STA/P2P-CLI
2. Turn on the above concurrency combinations in diff band
3. The expectation should be MCC as DBS for this combination
is disabled, but this is not the observation.

here the vdev that comes up next, would fail as MCC is rejected
in policy_mgr_is_hwmode_set_for_given_chn, and DBS is not allowed
according to the check in policy_mgr_is_dbs_allowed_for_concurrency
hence the combination mentioned above cannot be achieved with
this check.

Fix is to remove the check of dbs from API
policy_mgr_is_hwmode_set_for_given_chnl.
