Jonathan Rico 7093538c42 Bluetooth: att: don't re-use the ATT buffer for confirmations 
If the peer is a zephyr host, there is no problem, as the Zephyr
host limits sending parallel REQs and INDs.

But the spec allows sending those in parallel, and it may end up that
the re-used REQ buffer hasn't been destroyed when an indication comes.

Only re-use the buffer when enqueuing ATT responses.

This means that we may run out of buffers if the peer sends too many
indications and our application also sends a lot of commands/notifications.

The rationale for this is that having to handle a lot of requests is a
more plausible scenario (e.g. being discovered by multiple peers) than
handling lots of parallel indications.
