qcacld-3.0: Remove CDS fw_state handling

Previous change I8331367dd41dd0cedfa65c63f1bb3ffcb535e1c9
("qcacld-3.0: Call icnss API to check if WLAN FW is down") relocated
the source of firmware status from the wlan driver to the platform
driver. The legacy fw_state handling in CDS is no longer used, so
remove it.
