net: dsa: microchip: ksz8: ksz8_fdb_dump: avoid extracting ghost entry from empty dynamic MAC table.

Browse Source 
[ Upstream commit 492606cdc7 ]

If the dynamic MAC table is empty, we will still extract one outdated
entry. Fix it by using correct bit offset.

Fixes: 4b20a07e10 ("net: dsa: microchip: ksz8795: add support for ksz88xx chips")
