qcacld-3.0: Rectify possible scenario of double free
Presently in the driver, in function hdd_objmgr_create_and_store_vdev
the vdev object is created and stored. In case the creation of the vdev
fails due to some reason, the corresponding error condition tries to
free the osif_priv pointer. This osif_free pointer is actually already
freed as a part of vdev_obj_delete -> vdev_release_ref -> vdev_obj_free.
As this is already freed, a possible double free scenario can occur in
the original error handling scenario.
To avoid this scenario, do not free the osif_priv pointer in the error
handling as it is already taken care in the caller.
