qcacld-3.0: Remove DPU signatures from struct csr_roam_info

In a prior version of the driver DPU signatures were used to
synchronize the Data Plane with the Control Plane. The DPU signatures
were provided to HDD by SME via fields in struct csr_roam_info, and
then HDD provided the fields to the Data Plane. But that mechanism is
no longer used and HDD does not read these fields so remove them along
with the logic that is currently used to fill them.
