qcacld-3.0: Ensure the fw parameters are restored

Propagation from qcacld-2.0 to qcacld-3.0.

It is the regression issue caused by ChangeId
I6223ab27c2285c53c45fd388bd56cadc6d348324. When changing
the TX_WAKE_THRESHOLD to TX_WAKE_THRESHOLD_NEVER, the
function wmi_unified_set_sta_ps_param will set
iface->ps_enabled to FALSE. Because of this in function
wma_set_vdev_resume_dtim, "iface->ps_enabled == TRUE"
check fails which is not expected.

To mitigate this issue, remove the unnecessary code
related to iface->ps_enabled.
