qcacld-3.0: Remove redundant code of hw dbs capable

Currently the driver has hdd, sme api to set the hw
dbs capability in the mac context which is not used
by any other module, because the dispatcher APIs are
already present.

Remove the hw mode capability variable from the mac
context as it is no longer used.
