qcacld-3.0: Avoid using struct csr_roam_session in lim

struct csr_roam_session is used in LIM in func
lim_get_session_by_macaddr to get if SA is same as one of the vdev.

struct csr_roam_session should not be used by LIM, so raise change
to used vdev obj manager to find a vdev with same MAC address.
