qcacld-3.0: Remove obsolete use of DPU signatures
In a previous version of the driver both unicast and broadcast DPU
signatures were used to synchronize the data plane with the control
plane. However the current version of the driver does not use this
synchronization mechanism, so remove propagation of the DPU signatures
from the UMAC. This is part of the plan to completely remove these
signatures from throughout the driver.
