[PATCH] bios: hda_audio: skip the test if audio devices don't exist (LP: #1285571)

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

When running this test on an ARM server that did not have any sound
devices this test just silently did nothing. This small fix makes
the test report that it could not find any audio devices and will
mark the test as skipped.
