qcacld-3.0: Fix link speed state always keep bad issue

After setting link speed threshold to low value like 10 Mbps by vendor cmd,
in bus bw timer, when find link speed above theshold, just change local
link speed state to good, not update global var dp_intf->link_monitoring,
so link_monitoring_cb is called periodically, message to update link
speed to good is sent to scheduler thread periodically,
WMI_ROAM_SET_PARAM_CMDID is sent to F/W periodically too.

To fix it, when find link speed state change from bad to good, update to
global var dp_intf->link_monitoring too. In next bus bw timer, find link
speed state keep good, don't send msg to update link speed again.
