lantiq_gswip: Two small fixes

While updating the Lantiq target in OpenWrt to Linux 5.15 I came across
an FDB related error message. While that still needs to be solved I
found two other small issues on the way.

This series fixes the two minor issues found while revisiting the FDB
code in the lantiq_gswip driver:
- The first patch fixes the start index used in gswip_port_fdb() to
  find the entry with the matching bridge. The updated logic is now
  consistent with the rest of the driver.
- The second patch fixes a typo in a dev_err() message.
