qcacld-3.0: Fix uninitialized subtype usage by policy manager

Currently, Updation of vdev related parameters
policy_mgr_vdev_entry_info is conditional. Conditional
updation can cause uninitialized usage of subtype of
policy_mgr_vdev_entry_info by policy manager to get concurrency
mode.

Fix is to initialize policy_mgr_vdev_entry_info with zero.
