[PATCH 5.12 027/700] usb: typec: Add the missed altmode_id_remove() in typec_register_altmode()

[Greg Kroah-Hartman]

From: Jing Xiangfeng <jingxiangfeng@xxxxxxxxxx>

commit 03026197bb657d784220b040c6173267a0375741 upstream.

typec_register_altmode() misses to call altmode_id_remove() in an error
path. Add the missed function call to fix it.

Fixes: 8a37d87d72f0 ("usb: typec: Bus type for alternate modes")
