net: dsa: microchip: ksz8: fix ksz8_fdb_dump()
[ Upstream commit 88e943e83827a349f70c3464b3eba7260be7461d ]
Before this patch, the ksz8_fdb_dump() function had several issues, such
as uninitialized variables and incorrect usage of source port as a bit
mask. These problems caused inaccurate reporting of vid information and
port assignment in the bridge fdb.
