[PATCH v4 4/4] net/zxdh: fix queue enable intr issues

[Junlong Wang]

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")
