hda_dai_suspend() was added to handle paused stream during system suspend. But as a side effect, it also ends up cleaning up the DMA data for those streams that were prepared but not triggered before a system suspend. Since these streams will not receive the prepare callback after resuming, we need to preserve the DMA data during suspend. So, add the check to handle only those streams that are in the paused state to avoid losing the DMA data for all other streams.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
