Convert users of net_buf_put() and net_buf_get() functions to use
non-wrapped putters and getters k_fifo_put() and k_fifo_get().
Special handling of net_bufs in k_fifos is no longer needed after commit
3d306c181f, since these actions are now
atomic regardless of any net_buf fragments.

Check whether the received frame is complete by
comparing the length of the received data with
the frame data.

Due to the sending buf cannot be referred
by sending layer.
It is unsafe to use `buf` identification
for a transmission, because the buf may
have been newly transmitted when the
sent callback is triggered.
Now instead, when the send completion
callback is received, the upper layer
is notified that a transfer is completed.
If multiple bufs are sent at the same
time, there is no guarantee which buf
is completed when the sent callback
triggered. Therefore, it is recommended
that the caller transfers the next data
block after the previous transfer is
completed.

There is a change (commit no.: 93d0eac834) that if
the `ref` of sending buf is not 1, the error code
`-EINVAL` will be returned from bt_conn_send_cb.
It causes the RFCOMM functionality cannot work
properly.
Remove the ref operation from the buf to be sent
to fix the issue.

Currently, the upper layer cannot know
whether the data is successfully sent
through DLC.
Add a field "sent" for RFCOMM DLC ops.
Notify upper-layer of the sending
result through the field "sent".
