net: dsa: fix dereference on ds->dev before null check error
Currently ds->dev is dereferenced on the assignments of pdata and
np before ds->dev is null checked, hence there is a potential null
pointer dereference on ds->dev. Fix this by assigning pdata and
np after the ds->dev null pointer sanity check.
Addresses-Coverity: ("Dereference before null check")
Fixes: 7e99e3470172 ("net: dsa: remove dsa_switch_alloc helper")
