net/mlx5e: Nullify table pointer when failing to create
[ Upstream commit 1b540decd03acd736693aabb6cb46c71fca38ae6 ]
On failing to create promisc flow steering table, the pointer is
returned with an error. Nullify it so unloading the driver won't try to
destroy a non existing table.
Failing to create promisc table may happen over BF devices when the ARM
side is going through a firmware tear down. The host side start a
reload flow. While the driver unloads, it tries to remove the promisc
table. Remove WARN in this state as it is a valid error flow.
Fixes: 1c46d7409f30 ("net/mlx5e: Optimize promiscuous mode")
