sfc: Split MAC stats DMA initiation and completion
From: Steve Hodgson <shodgson@solarflare.com>
Currently we initiate MAC stats DMA and busy-wait for completion when
stats are requested. We can improve on this with a periodic timer to
initiate and poll for stats, and opportunistically poll when stats are
requested.
Since efx_nic::stats_disable_count and efx_stats_{disable,enable}()
are Falcon-specific, rename them and move them accordingly.
