qcacld-3.0: Send peer delete wmi cmd before peer detach

This is a qcacld-2.0 to qcacld-3.0 propagation.

In wma_remove_peer, sometimes when peer detach is in progress,
and it has set the peer as invalid, but WMI_PEER_DELETE_CMDID
is still not sent to FW, so msdu for the peer still can be
received. In htt_rx_amsdu_rx_in_order_pop_ll, it will print
a lot of error log, which will cause watch dog.

Send peer delete cmd to FW firstly, then detach peer in host.

In qcacld-3.0, it doesn't have watch dog issue, as the print has
been removed from htt_rx_amsdu_rx_in_order_pop_ll, but it is still
worth to adjust to the right sequence.
