Subject: be2net: re-order fields in be_error_recovert to avoid hole
Patch-mainline: v4.19-rc1
Git-commit: 03d231a963ae1179d05f552db75b661d1099272f
References: bsc#1104714 FATE#325913

- Unionize two u8 fields where only one of them is used depending on NIC
chipset.
- Move recovery_supported field after that union

These changes eliminate 7-bytes hole in the struct and makes it smaller
by 8 bytes.
