net/mlx5e: CT, Avoid false lock dependency warning
To avoid false lock dependency warning set the ct_entries_ht lock
class different than the lock class of the ht being used when deleting
last flow from a group and then deleting a group, we get into del_sw_flow_group()
which call rhashtable_destroy on fg->ftes_hash which will take ht->mutex but
it's different than the ht->mutex here.
======================================================
WARNING: possible circular locking dependency detected
5.10.0-rc2+ #8 Tainted: G O
------------------------------------------------------
revalidator23/24009 is trying to acquire lock:
ffff888128d83828 (&node->lock){++++}-{3:3}, at: mlx5_del_flow_rules+0x83/0x7a0 [mlx5_core]
but task is already holding lock:
ffff8881081ef518 (&ht->mutex){+.+.}-{3:3}, at: rhashtable_free_and_destroy+0x37/0x720
which lock already depends on the new lock.
