[PATCH] usb: typec: tipd: Zero-initialize CD321x partner descriptor

[Sven Peter <sven@kernel.org>]

The typec_partner_desc struct isn't initialized and instead filled with
whatever values happen to be on the stack. We especially don't overwrite
the attach/detach callbacks. Just zero initialize it to make sure we don't
run into weird issues in the future.

Fixes: 82432bbfb9e8 ("usb: typec: tipd: Handle mode transitions for CD321x")

I deliberately didn't cc stable@ since we can't even reach the path
that would try to run these callbacks on platforms where this is used.
Just noticed this while working on the USB4/Thunderbolt series for Apple
Silicon.
