SnapdragonCamera: Fix front camera and scene mode picture taking issues

Fix front camera picture taking issues.
Fix scene mode picture taking issues.
For both front camera and scene mode issue, focus state was not
updating properly so it was stuck waiting for focus to finish.
So added another logic to check such case and continue to next step.
