qcacld-3.0: Remove check for DBS HW mode

Browse source 
Currently the driver checks whether hw is
already in DBS in the function
policy_mgr_check_and_set_hw_mode_for_channel_switch
and it does not set hw mode if it is already
in DBS mode. It can happen that SMM is already
requested and is present in serialization and it
would change the HW mode from DBS->SMM and if
driver starts any vdev on 2.4ghz in HST/HSP
which requires the DBS mode for 2.4ghz , the FW
would send a vdev start failure.

Fix is to remove the check of current hw mode and
let DBS be posted to serialization. If hw mode is
already in DBS it would return from serialization
with E_ALREADY but would ensure that HW mode is
always in DBS for a 2.4ghz connection.
