[PATCH] ASoC: Intel: sst: Fix firmware resource leak in sst_request_fw()

[aravindanilraj0702]

From: Aravind Anilraj <aravindanilraj0702@xxxxxxxxx>

The sst_request_fw() function calls request_firmware() but does not
release the firmware on any return path, resulting in a resource leak.

Ensure release_firmware() is called after the firmware has been
processed to properly free the allocated resources.

This issue was identified by smatch.
