[PATCH 03/24] Revert "Bluetooth: Move rfcomm_get_device() before rfcomm_dev_activate()"

[Peter Hurley]

This reverts commit e228b63390536f5b737056059a9a04ea016b1abf.

This is the third of a 3-patch revert, together with
Revert "Bluetooth: Remove rfcomm_carrier_raised()" and
Revert "Bluetooth: Always wait for a connection on RFCOMM open()".

Commit 4a2fb3ecc7467c775b154813861f25a0ddc11aa0,
"Bluetooth: Always wait for a connection on RFCOMM open()" open-codes
blocking on tty open(), rather than using the default behavior
implemented by the tty port.

The reasons for reverting that patch are detailed in that changelog;
this patch restores required functionality for that revert.
