Subject: mlxsw: spectrum_nve: Remove easily triggerable warnings
Patch-mainline: v4.20-rc6
Git-commit: 050fc01fb1d916058605569cd7f4e15152afc3af
References: bsc#1112374

It is possible to trigger a warning in mlxsw in case a flood entry which
mlxsw is not aware of is deleted from the VxLAN device. This is because
mlxsw expects to find a singly linked list where the flood entry is
present in.

Fix by removing these warnings for now.

Will re-add them in the next release after we teach mlxsw to ask for a
dump of FDB entries from the VxLAN device, once it is enslaved to a
bridge mlxsw cares about.
