net: dsa: microchip: ksz8: fix ksz8_fdb_dump() to extract all 1024 entries

Browse source 
Current ksz8_fdb_dump() is able to extract only max 249 entries on
the ksz8863/ksz8873 series of switches. This happened due to wrong
bit mask and offset calculation.

This commit corrects the issue and allows for the complete extraction of
all 1024 entries.

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