[alsa-devel] patch for alsa-info.sh to quote [ -d $SYSFS ]

[Luis Yanes]

Found a couple of bugs in http://www.alsa-project.org/alsa-info.sh
while running it in my system.

* old uname <= 2.0.11 doesn't accept -o argument
* $SYSFS is not quoted while checking if directory exist and fails if
empty

Attached is a small patch for the first of them, but think that all
variables also should be quoted to avoid future problems.

Regards.
