Currently, host allows maximum MAX_NDP_INSTANCES_PER_PEER(2) NDPs
per peer. Framework may need more NDPs with the same peer when
multiple NDP applications are running. Firmware shall allow/reject
an NDP based on the max number of NDP connections allowed per peer.
It's platform specific and firmware shall take care of it.
Remove the check in host which limits this.
