sfc: replace asynchronous filter operations
Instead of having an efx->type->filter_rfs_insert() method, just use
workitems with a worker function that calls efx->type->filter_insert().
The only user of this is efx_filter_rfs(), which now queues a call to
efx_filter_rfs_work().
Similarly, efx_filter_rfs_expire() is now a worker function called on a
new channel->filter_work work_struct, so the method
efx->type->filter_rfs_expire_one() is no longer called in atomic context.
We also add a new mutex efx->rps_mutex to protect the RPS state (efx->
rps_expire_channel, efx->rps_expire_index, and channel->rps_flow_id) so
that the taking of efx->filter_lock can be moved to
efx->type->filter_rfs_expire_one().
Thus, all filter table functions are now called in a sleepable context,
allowing them to use sleeping locks in a future patch.
