[PATCH] Bluetooth: Update L2CAP timeout constants to use msecs_to_jiffies

[Marcel Holtmann <marcel@holtmann.org>]

The L2CAP timeout 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.
