Bluetooth: ISO: use correct CIS order in Set CIG Parameters event

[ Upstream commit 71e9588435c38112d6a8686d3d8e7cc1de8fe22c ]

The order of CIS handle array in Set CIG Parameters response shall match
the order of the CIS_ID array in the command (Core v5.3 Vol 4 Part E Sec
7.8.97).  We send CIS_IDs mainly in the order of increasing CIS_ID (but
with "last" CIS first if it has fixed CIG_ID).  In handling of the
reply, we currently assume this is also the same as the order of
hci_conn in hdev->conn_hash, but that is not true.

Match the correct hci_conn to the correct handle by matching them based
on the CIG+CIS combination.  The CIG+CIS combination shall be unique for
ISO_LINK hci_conn at state >= BT_BOUND, which we maintain in
hci_le_set_cig_params.
