[PATCH 2/4] ASoC: SOF: loader: fix memory leak in get_ext_windows

[Ranjani Sridharan]

From: Pierre-Louis Bossart <pierre-louis.bossart at linux.intel.com>

sdev->info_window is allocated with kmemdup and never freed, use devm_
version since this is only used for first boot.

Fixes: 8d809c15acf23 ('ASoC: SOF: ext_manifest: parse windows')
