fstests: btrfs/091: Disable compress to avoid output dismatch

Commit Message

Qu Wenruo April 12, 2016, 7:59 a.m. UTC

If run btrfs/091 with "-o compress=lzo" mount option, test case will
fail, as compress makes extent much smaller on disk, making output
different from golden output.

As this test case is only testing qgroup, not compression, disable
compression manually in test case.
