qcacld-3.0: Parse device info nl attribute in the oem vendor cmd

Userspace uses enum qca_vendor_oem_device_type to indicate
device type as vdev or pdev in the oem data vendor nl command.

This attribute is set to 1 to indicate that the oem data command
is meant for pdev and it is 0 for vdev. The default is vdev when
this nl attribute is not present.

The host driver should update the pdev_id of the vdev and fill
the pdev_vdev_flag to 1 for pdev commands.
