sfc: don't try and read ef10 data on non-ef10 NIC
The MAC stats command takes a port ID, which doesn't exist on
pre-ef10 NICs (5000- and 6000- series). This is extracted from the
NIC specific data; we misinterpret this as the ef10 data structure,
causing us to read potentially unallocated data. With a KASAN kernel
this can cause errors with:
BUG: KASAN: slab-out-of-bounds in efx_mcdi_mac_stats
Fixes: 0a2ab4d988d7 ("sfc: set the port-id when calling MC_CMD_MAC_STATS")
