alsa-info.sh: Remove progress spinner during upload without dialog

The spinner did not actually provide information about the status
of the file upload, and caused other problems: it would repeatedly
spawn new pgrep processes (without a delay between them), and it
blocked the script if any wget process was running on the system.
