drivers/ec/vboot_aux_fw: Remove tunnel protect_status operation

TCPC FW update is performed immediately after checking the need for FW
update. Remote bus tunnel protection status is checked at both times and
is redundant. Remove the redundant protect_status operation and invoke
it directly just before applying the FW update.
