Fix remote submix crash on null sink
The "remote submix" HAL uses a MonoPipe instance to "pipe" audio
from the sink of this virtual device HAL to its source.
The life-cycle of this pipe is:
- creation when either the input or output stream is open
- destruction when both input and output are closed.
Changes are:
Fix test for pipe destruction: destroy pipe when both
input and output streams are NULL.
Count how many read errors went into the logs and cap them
so as not to spam the logs when the pipe is not properly
set up. Less 'I' logs, 'D' logs instead.
When opening input stream, check for non-null sink before
checking if it's shutdown.
