qcacmn: Limiting a function declaration within CONFIG_MCL

Function dbglog_set_log_lvl needs to be commented out for WIN compilation
since enum DBG_LOG_LVL is not converged. Functions nl_srv_bcast and
nl_srv_is_initialized needs to be exported out for pushing FW Diag Log
events to user-space (cnss-diag)
