ramips: Add missing andmask to ramips_esw register read for recv_good value.
Add missing andmask to ramips_esw register read for recv_good value.
Without the mask, recv_bad leaks into the recv_good packet count.
Didn't notice the bug before since you don't usually get bad
packets, so I only saw it when I was playing with overlength packets
earlier...
