qcacld-3.0: Remove usage of datapath handles in outer layers

Currently many layers store the datapath handles i.e.
pdev and vdev handles and use them for passing as an
argument to the CDP APIs. This gives way to possible
race conditions, where the datapath handle provided by
the outer layer might be a stale pointer, which in turn
leads to unexpected results.

Remove the storage and usage of all the datapath handles
from the layers currently using them.

- vdev objmgr
