net: dsa: b53: b53_arl_rw_op() needs to select IVL or SVL

BugLink: https://bugs.launchpad.net/bugs/1876361
[ Upstream commit 64fec9493f7dc9bdd7233bcfe98985c45bd0e3c1 ]

Flip the IVL_SVL_SELECT bit correctly based on the VLAN enable status,
the default is to perform Shared VLAN learning instead of Individual
learning.
