generic/269: require no compression

This is meant to test ENOSPC, but we're dd'ing /dev/zero, which won't
fill up anything with compression on.

Additionally we're killing dd and then immediately trying to unmount.
With compression we could have references to the inode being held by the
async compression workers, so sometimes this will fail with EBUSY on the
unmount.

A better test would be to use slightly compressible data; use _ddt.
