soc: qcom: glink_smd_xprt: Sync probe wait status with close



A closed channel is no longer waiting on the probe of the underlying SMD
pipe.  The probe wait status is not updated when the channel is closed
which can lead to the wrong code path being executed if the probe occurs.

Sync the probe wait status of the channel with the close status of the
channel so that the correct code path is run if the probe were to occur
after channel close.
