[PW_SID:1078747] Bluetooth: hci_conn: validate connection before BIG creation

[BluezTestBot]

Add missing hci_conn_valid() check in create_big_sync() to prevent
a potential use-after-free. The connection object passed via
hci_cmd_sync_queue() could be freed before the async callback
executes, leading to a dereference of stale memory.

All other async callbacks using the same pattern already validate
the connection (e.g. hci_le_big_create_sync, hci_acl_create_conn_sync,
hci_le_create_conn_sync, abort_conn_sync).
