qcacld-3.0: Add ini config for tx mgmt frame rate

qcacld-2.0 to qcacld-3.0 propagation

Add an ini option for configuring rate for tx mgmt frame.
It sets the existed wmi cmd: WMI_VDEV_PARAM_MGMT_TX_RATE right
after vdev created. Since FW resets mgmt during vdev up, also
set mgmt rate after sap/sta vdev up.
