[dpdk-dev] [PATCH 09/10] net/e1000: add function return value check

[Min Hu (Connor)]

From: HongBo Zheng <zhenghongbo3 at huawei.com>

Return value of a function 'e1000_phy_has_link_generic'
called at e1000_kmrn_lock_loss_workaround_ich8lan is not
checked, but it is usually checked for this function.

This patch fix this problem.

Fixes: 5a32a257f957 ("e1000: more NICs in base driver")
