The zed's io-spare.sh script defines a vdev_status() function to query
the 'zpool status' output for obtaining the status of a specified vdev.
This function contains a small awk script that uses a parameter
expansion (${parameter/pattern/string}) supported in bash but not
in dash. Under dash, this fails with a "Bad substitution" error.
This commit replaces the awk script with a (hopefully more portable)
sed script that has been tested under both bash and dash.
