qcacld-3.0: Fix invalid malloc in lim_cm_fill_link_session

When roaming from legacy AP to MLO AP, during the pe session
creation for the link vdev, the bss descriptor is allocated in
lim_cm_fill_link_session(), but its already allocated as part of
lim_join_req allocation and is not freed.

Don't allocate memory for bss_desc pointer again in
lim_cm_fill_link_session() api.
