[PATCH 5.7 039/265] net: macb: undo operations in case of failure

[Sasha Levin]

From: Claudiu Beznea <claudiu.beznea@xxxxxxxxxxxxx>

[ Upstream commit faa620876b01d6744f1599e279042bb8149247ab ]

Undo previously done operation in case macb_phylink_connect()
fails. Since macb_reset_hw() is the 1st undo operation the
napi_exit label was renamed to reset_hw.

Fixes: 7897b071ac3b ("net: macb: convert to phylink")
