usb: typec: Fix error pointer dereference

The variable tps->partner is checked for an error pointer and then if it is, it sends an error message but does not return and then immediately dereferenced a few lines below:

tps->partner = typec_register_partner(tps->port, &desc); if (IS_ERR(tps->partner)) dev_warn(tps->dev, "%s: failed to register partnet\n", __func__);

if (desc.identity) { typec_partner_set_identity(tps->partner); cd321x->cur_partner_identity = st.partner_identity; }

Add early return and fix spelling mistake in error message.
