Subject: net: macb: undo operations in case of failure
Git-commit: faa620876b01d6744f1599e279042bb8149247ab
Patch-mainline: v5.8-rc3
References: jsc#SLE-12251
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")
