Revert "Alsa: fix crash when detecting devices."

Browse Source 
This reverts commit 0ab81ef59f.
The workaround causes software devices not to appear in the list
of available devices. Besides, since the crash is caused by a bug
in older versions of Alsa, the workaround was probably a bad idea
in the first place. People should update Alsa instead.

Task-number: QTBUG-42326
