[ Upstream commit e77b259f67ab99f1e22ce895b9b1c637fd5f2d4c ]
In gbaudio_dapm_free_controls(), if one of the widgets is not found, an error
will be returned directly, which will cause the rest to be unable to be freed,
resulting in leak.
This patch fixes the bug. If if one of them is not found, just skip and free
the others.
Fixes: 510e340efe0c ("staging: greybus: audio: Add helper APIs for dynamic
audio module")
