Bluetooth: Mesh: Fixes LPN poll timeout gradually grow

Browse source 
`POLL_TIMEOUT_MAX` should use `CONFIG_BT_MESH_LPN_POLL_TIMEOUT`
instead of `CONFIG_BT_MESH_LPN_INIT_POLL_TIMEOUT`. The described
algorithm to grow the poll timeout implemented in function
poll_timeout does not work with this implementation.

It's a regression in 3b4d58a
