Revert "usb: typec: ucsi: check partner changed flag during notification"



This reverts commit 1bed1828.

When boot up without USB cable, UCSI_GET_CONNECTOR_STATUS command
will return all zero message,

Example UCSI IPC log:
40.319381997:   sync_write: CONTROL: 12 00 01 00 00 00 00 00
40.319507987:   read: CCI: 00 09 00 80
40.319620018:   read: MSG_IN: 00 00 00 00 00 00 00 00 00

the change will block this message notify client, so revert it.
