qcacld-3.0: Fix bad pointers being passed from SME to WMA

In commit d217d19d7e59 ("qcacld-3.0: Add vendor cmd to support
antenna diversity") and commit 66831666b4a5 ("qcacld-3.0: Add
vendor attr to get rx aggregation statistics"), tHalHandle (pMac)
are passed by SME to WMA APIs that expect a tp_wma_handle.

To fix this, call cds_get_context() to get wma handle.
