Bluetooth: l2cap_set_timer needs jiffies as timeout value

After moving L2CAP timers to workqueues l2cap_set_timer expects timeout
value to be specified in jiffies but constants defined in miliseconds
are used. This makes timeouts unreliable when CONFIG_HZ is not set to
1000.

__set_chan_timer macro still uses jiffies as input to avoid multiple
conversions from/to jiffies for sk_sndtimeo value which is already
specified in jiffies.
