qcacld-3.0: Fix SSR failure on Rome

Peer and vdev leaked during SSR, Helium/Rome SSR is different.
Helium:
FW assert will indicate to CNSS driver, then PLD_FW_DOWN
is sent, in wlan_hdd_pld_uevent, target ready is cleared and
RECOVERING is set, so wma_force_objmgr_vdev_peer_cleanup can be
called, no such issue.
Rome:
FW assert will indicate to wlan driver directly, in
ol_target_failure, only RECOVERING is set, target ready isn't
cleared, wma_force_objmgr_vdev_peer_cleanup can't be called,
so peer and vdev leaked.
