[PATCH net-next 6/9] ice: cleanup rules info

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Victor Raj <victor.raj@intel.com>

Change ICE_SW_LKUP_LAST to ICE_MAX_NUM_RECIPES as for now there also can
be recipes other than the default.

Free all structures created for advanced recipes in cleanup function.
Write a function to clean allocated structures on advanced rule info.
