soc: qcom: hab: fix the leak risk in hab_vchan_get
When getting a vchan after receiving a message, it has probability that
this vchan is closed concurrently. So when refcount is increased by
kref_get_unless_zero, but flag vchan->otherend_closed or vchan->closed
is true at this time, it will return vchan as NULL, and the hab_vchan_put
will not be called in hab_msg_rev. So adjust the timing here can avoid the
leak risk.
