[ Upstream commit d8251b9db34a2cbc5619b610e7e8aad1d165c531 ]

We were checking that the MC (member config) was != 0
for some reason, all we need to check is that the config
has no ports, i.e. no members. Then it can be recycled.
This must be some misunderstanding.

Fixes: 4ddcaf1ebb5e ("net: dsa: rtl8366: Properly clear member config")
