Before issuing the LE BIG Create Sync command, an available BIG handle
is chosen by iterating through the conn_hash list and finding the first
unused value.
If a BIG is terminated, the associated hcons are removed from the list
and the LE BIG Terminate Sync command is sent via hci_sync queue.
However, a new LE BIG Create sync command might be issued via
hci_send_cmd, before the previous BIG sync was terminated. This
can cause the same BIG handle to be reused and the LE BIG Create Sync
to fail with Command Disallowed.

This commit fixes the ordering of the LE BIG Create Sync/LE BIG Terminate
Sync commands, to make sure that either the previous BIG sync is
terminated before reusing the handle, or that a new handle is chosen
for a new sync.
