ASoC: Intel: boards: always check the result of acpi_dev_get_first_match_dev()

BugLink: https://bugs.launchpad.net/bugs/2089884

[ Upstream commit 14e91ddd5c02d8c3e5a682ebfa0546352b459911 ]

The code seems mostly copy-pasted, with some machine drivers
forgetting to test if the 'adev' result is NULL.

Add this check when missing, and use -ENOENT consistently as an error
code.
