Krzysztof Kozlowski fefce5299e soundwire: debugfs: fix unbalanced pm_runtime_put() ...

[ Upstream commit 217f5e0de3 ]

If pm_runtime_resume_and_get() failed with -EACCES, the driver continued
execution and finally called pm_runtime_put_autosuspend().  Since
pm_runtime_resume_and_get() drops the usage counter on every error, this
lead to double decrement of that counter.
