Description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5: HWS, Handle destroying table that has a miss table

If a table has a miss table that was created by 'mlx5hws_table_set_default_miss' API function, its miss_tbl keeps the table that points to it in a list. If such table is deleted, we need to also remove it from the miss_tbl list, otherwise the node in miss_tbl list will contain garbage.
