Bluetooth: Fix not sending L2CAP Connection Parameters Update Request

This fixes issue that L2CAP Connection Parameters Update Request was
not sent. There was check that used LE features of host controller
to determine if L2CAP procedure or LL shall be used. It was failing
with 4.2 controller. The check shall test if remote supports
LL Connection Parameters Request Procedure. If it's not supported,
then L2CAP Connection Parameters Update Procedure will be used.

Closes ZEP-1220
