[PATCH v11 1/4] net/zxdh: fix queue enable intr issues

Fix incorrect condition check in zxdh_queue_enable_intr.
Change "==" to "!=", consistent with zxdh_queue_disable_intr logic,
to properly enable interrupts when event_flags_shadow is not
already set to ENABLE state.
Fixes: 7677f3871ef3 ("net/zxdh: setup Rx/Tx queues and interrupt")
