sfc: ef10: fix TX queue lookup in TX event handling
We're starting from a TXQ label, not a TXQ type, so
efx_channel_get_tx_queue() is inappropriate. This worked by chance,
because labels and types currently match on EF10, but we shouldn't
rely on that.
Fixes: 12804793b17c ("sfc: decouple TXQ type from label")
