net/hns3: fix ignored reset event

[ upstream commit 4c40006c4b6b3c567185c84d60535752c9f7ea3d ]

The code logic that only new reset whose level is higher than old
reset level will be addressed is added in 'hns3_detect_reset_event()',
in fixed commit.

When the new reset is detected and the old reset level is
HNS3_NONE_RESET this reset will be ignored. This patch fix it.
