Bluetooth: hci_core: Fix hci_conn_hash_lookup_cis

Browse Source 
[ Upstream commit 50efc63d1a ]

hci_conn_hash_lookup_cis shall always match the requested CIG and CIS
ids even when they are unset as otherwise it result in not being able
to bind/connect different sockets to the same address as that would
result in having multiple sockets mapping to the same hci_conn which
doesn't really work and prevents BAP audio configuration such as
AC 6(i) when CIG and CIS are left unset.
