[Wolverine LC] sfps number from chassis_api mismatch with platform.json

[wenyiz2021]

platform.json for wolverine linecard has 48 osfps: https://github.com/sonic-net/sonic-buildimage/blob/master/device/arista/x86_64-arista_7800r3a_36d2_lc/platform.json whereas chassis api returns 36 osfps. Can you please confirm which one is correct?

pytest_assert(num_sfps == expected_num_sfps,
"Number of sfps ({}) does not match expected number ({})"
>                         .format(num_sfps, expected_num_sfps))
E           Failed: Number of sfps (36) does not match expected number (48)
