storage_test scans all disks with parted

[Rod Smith]

The storage_test script includes the following line:

    size=`parted -l -s |grep "Disk.*${disk}" |awk '{print $3}'`

The call `parted -l -s` causes parted to scan ALL the disks in the system, and grep then extracts the desired data. This is fine in a way; however, if parted encounters a problem on ANY disk, it may emit a warning that will end up in the test output for the disk on which the script was called. This has shown up in, e.g.:

https://certification.canonical.com/hardware/201511-19982/submission/114848/test/363/result/8427219/

This output includes the following lines:

/dev/sdb is a block device
Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.

The warning, though, applies to /dev/sdc, whereas the test was run on /dev/sdb.

The solution is simple: Replace "parted -l -s" with "parted -s ${disk}", which restricts parted's actions to the specified disk device.

This script has been re-worked and does not use parted anymore. Marking invalid.
