net: dsa: realtek: rtl8366rb: Fix up port isolation

Sashiko reports that we incorrectly disable isolation in the setup
loop while what we want to do is to enable it.

Enable it by unconditionally setting the enable bit 0 in
rtl8366rb_port_set_isolation() so a mask of 0 when passed in
will enable isolation and isolate from ALL ports.

Fix up the comments so it is clear what is going on, including a
missing word in the helper function.
