qcacld-3.0: Iterate all links in shutdown and reset adapter

Iterate through all the active links in adapter in the following
APIs to loop the VDEVs.
1) hdd_reset_all_adapters()
2) wlan_hdd_auto_shutdown_enable()

The below API is changed to take link info pointer as function
argument
1) hdd_send_twt_del_all_sessions_to_userspace()

Change-Id: I689037a11c86602e7f9a2cd1f0b66ddeaa1a4228
CRs-Fixed: 3523139
