CVE-2024-42132

bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX

In the Linux kernel, the following vulnerability has been resolved:

bluetooth/hci: disallow setting handle bigger than HCI_CONN_HANDLE_MAX

Syzbot hit warning in hci_conn_del() caused by freeing handle that was
not allocated using ida allocator.

This is caused by handle bigger than HCI_CONN_HANDLE_MAX passed by
hci_le_big_sync_established_evt(), which makes code think it's unset
connection.

Add same check for handle upper bound as in hci_conn_set_handle() to
prevent warning.
