Reroute submix HAL: fix race condition on output state
When reading from a pipe, the output may have been previously
closed, therefore the output state should only be read if it
is still available.
This fixes a race condition observed between in_read() (which
accesses the output stream) and adev_close_output_stream()
(which sets the output reference to NULL).
No issue with out_write() which checks the input reference.
