[PATCH net mlxsw v3 3/4] mlxsw: core_acl_flex_actions: Remove redundant counter destruction

[Nir Dotan]

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")
