qcacld-3.0: Fix check in wlan_hdd_tsf_reg_update_details API

Currently in wlan_hdd_tsf_reg_update_details there is check for
change in tsf_id and mac_id, If current and new values are same
tsf_details_valid bit will not be set (In case of tsf_id = 0 and
mac_id = 0), which we result in host continuously reading via WMI
command instead of scratch register.

So to Fix the issue only check for tsf_id_valid and update the
values.
