[PATCH 2/9] net/txgbe: fix interrupt enable mask

[Jiawen Wu]

When using no LSC mode, GPIO interrupt can still cause
txgbe_dev_interrupt_delayed_handler() to be called, with
TXGBE_FLAG_NEED_LINK_UPDATE to be set. So add a LSC condition on
intr->mask_misc.

Fixes: 2fc745e6b606 ("net/txgbe: add interrupt operation")
Fixes: d3bb4a04eac1 ("net/txgbe: add SFP hotplug identification")
