The memory for mark table is allocated during port start.
But the allocated memory is freed only during port close
or driver unload which in turn causes a memory leakage
on each port start/stop.

Fixed it by moving the memory free to port stop.

Fixes: 4e40794a18a7 ("net/bnxt: add support for flow mark action")
