thunderbolt: Send uevent after asymmetric/symmetric switch

Browse source

commit 5391bcfa56 upstream.

We should send uevent to userspace whenever the link speed or width
changes but tb_switch_asym_enable() and tb_switch_asym_disable() set the
sw->link_width already so tb_switch_update_link_attributes() never
noticed the change.

Fix this so that we let tb_switch_update_link_attributes() update the
fields accordingly.
