net: dsa: microchip: ksz8: fix MDB configuration with non-zero VID 

[ Upstream commit 9aa5757e1f ]

FID is directly mapped to VID. However, configuring a MAC address with a
VID != 0 resulted in incorrect configuration due to an incorrect bit
mask. This kernel commit fixed the issue by correcting the bit mask and
ensuring proper configuration of MAC addresses with non-zero VID.
