Improve debugging of hci_conn objects by: adding print to hci_conn
refcounting, adding object spcifier when missing, change conn to hcon
since conn is heavily used for l2cap_conn objects and this is misleading.

The HCI constants are always used in form of jiffies. So just
include the conversion from msecs in the define itself. This has the
advantage of making the code where the timeout is used more readable
and avoiding unnecessary conversions.

The patch is similar to commit ba13ccd9 doing the same job for L2CAP

We initialize the "struct device" in hci_alloc_dev() for a long time now
so we can access hdev->dev.parent directly. Hence, we can drop the
temporary field hdev->parent which is used in no other place than
hci_add_sysfs().

SET_HCIDEV_DEV() is never called after registering a device by the
drivers so we do not overwrite internal device-state. Furthermore,
hdev->dev is initialized to 0 by kzalloc() inside hci_alloc_dev() so the
default behavior with dev.parent = NULL is kept.
