[PATCH 2/2] ASoC: wm_adsp_fw_find_test: Clear searched_fw_files in find-by-index test

[Richard Fitzgerald]

In wm_adsp_fw_find_test_find_firmware_byindex() the content of
priv->searched_fw_files must be cleared before starting the next iteration.

The files searched for are appended to priv->searched_fw_files, so if it is
not cleared on each iteration it will still contain the searches from the
previous iteration.
