[RFC] Bluetooth: Remove duplicated code in l2cap conn req

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

The same sequence sending L2CAP Connection Request was
used in several places. Using subroutine makes those
places easy to read.
