[patch net 2/2] net: sched: return -ENOENT when trying to remove filter from non-existent chain

[Jiri Pirko]

From: Jiri Pirko <j...@mellanox.com>

When chain 0 was implicitly created, removal of non-existent filter from
chain 0 gave -ENOENT. Once chain 0 became non-implicit, the same call is
giving -EINVAL. Fix this by returning -ENOENT in that case.
