Subject: [PATCH net-next 0/2] net: dsa: don't unmask port bitmaps

DSA has several bitmaps to store the type of ports: cpu_port_mask,
dsa_port_mask and enabled_port_mask. But the code is inconsistently
unmasking them.

The legacy code tries to unmask cpu_port_mask and dsa_port_mask but
skips enabled_port_mask.

The new bindings unmasks cpu_port_mask and enabled_port_mask but skips
dsa_port_mask.

In fact there is no need to unmask them because we are in the error
path, and they won't be used after. Instead of fixing the unmasking,
simply remove them.
