Victor Nogueira ed303cc7aa net/sched: act_api: Notify user space if any actions were flushed before error
commit 76b39b9438 upstream.

If during an action flush operation one of the actions is still being
referenced, the flush operation is aborted and the kernel returns to
user space with an error. However, if the kernel was able to flush, for
example, 3 actions and failed on the fourth, the kernel will not notify
user space that it deleted 3 actions before failing.

This patch fixes that behaviour by notifying user space of how many
actions were deleted before flush failed and by setting extack with a
message describing what happened.

Fixes: 55334a5db5 ("net_sched: act: refuse to remove bound action outside")
