fstests: btrfs/082: Check return value of "btrfs filesystem show" command executed on umounted device.

Commit Message

Qu Wenruo Jan. 21, 2015, 6:08 a.m. UTC

The return value should always be 0 if no problem happens, but
"btrfs filesystem show" executed on umounted device will always return 1
even there is no problem.

This testcase just checks it.
