qcacld-3.0: Don't enable eMLSR STA link when concurrent AP is UP

Currently, host driver disables eMLSR STA link when a SAP is
coming UP. Once the SAP is UP, host driver evaluates the current
concurrencies and re-enables the link if it can. This allows the
driver to bring UP disabled link(if any) as the SAP would do SCC
with one of the ML-STA links. But this is not applicable for
eMLSR STA. No other concurrency can co-exist with eMLSR STA
currently. So, one link has to be force-disabled always to let
the firmware not enter into eMLSR mode.
So, don't allow the validation of current concurrencies in
policy_mgr_handle_sap_cli_go_ml_sta_up_csa() eMLSR API
policy_mgr_handle_emlsr_sta_concurrency() takes care of
eMLSR concurrencies.
