qcacld-3.0: Remove serialization from open and close session
Remove serialization from sme_open_session and sme_close_session,
as these events are going to be serialized through following.
1) Two back to back open sessions can't come because kernel will
serialize using rtnl locks. Same goes for close sessions.
2) Even if two open sessions or close sessions comes back to back
from driver itself or from other sources then HDD will make-sure
of serialization through wait_for_completion_timeout call.
