Revert "Bluetooth: L2CAP: convert timeouts to secs_to_jiffies()"

This reverts commit c9d84da. It
replaces in L2CAP calls to msecs_to_jiffies() to secs_to_jiffies()
and updates the constants accordingly. But the constants are also
used in LCAP Configure Request and L2CAP Configure Response which
expect values in milliseconds.
This may prevent correct usage of L2CAP channel.

To fix it, keep those constants in milliseconds and so revert this
change.
