4.17-stable review patch. If anyone has any objections, please let me know.

From: Nir Dotan <nird@xxxxxxxxxxxx>
[ Upstream commit 7cc6169493990dec488eda0a3f6612729ca25e81 ]
Each tc flower rule uses a hidden count action. As counter resource may
not be available due to limited HW resources, update _counter_create()
and _counter_destroy() pair to follow previously introduced symmetric
error condition handling, add a call to mlxsw_afa_resource_del() as part
of the counter resource destruction.
Fixes: c18c1e186ba8 ("mlxsw: core: Make counter index allocated inside the action append")
