Subject: [PATCH] net/hns3: fix max packet size rollback in PF
HNS3 PF driver use the hns->pf.mps to restore the MTU when a reset
occurs.
If user fails to configure the MTU, the MPS of PF may not be restored to
the original value.
Fixes: 25fb790f7868 ("net/hns3: fix HW buffer size on MTU update")
Fixes: 1f5ca0b460cd ("net/hns3: support some device operations")
Fixes: d51867db65c1 ("net/hns3: add initialization")
