qcacld-3.0: Remove eWNI_SME_GET_ASSOC_STAS_REQ handling

Change I050383ce7e922fe4e42e1f5c4d2a8260dddbd4bb ("qcacld-3.0: Remove
csr_send_mb_get_associated_stas_req_msg()") removed the logic that
sent the eWNI_SME_GET_ASSOC_STAS_REQ message. Since this message is
obsolete, remove the handling code from LIM.

Change-Id: Iea602a1da42d5eecafae1d00f2260f4930128f40
