Subject: [PATCH] net: atlantic: fix overwritten return value in Aquantia driver

From: tian <27392025k@...il.com>

In hw_atl_utils.c and hw_atl_utils_fw2x.c, a return value is set and then
immediately overwritten by another call, which causes the original result
to be lost. This may hide errors that should be returned to the caller.

This patch fixes the logic to preserve the intended return values.
