soc: qcom: hab: add rx queue empty check after getting the lock

Need to do empty check again when we have the lock of the rx queue of
a given virtual channel. Without this check, it is possible that the
list head of the queue will be wrongly taken as a valid message node
if the valid message has already been fetched by some other thread.
