[PATCH] xfstests: 068: run fsstress in read/write mode

[Eric Sandeen]

Jan Kara was testing filesystem freeze, and was consistently locking
up, although my tests of 068 were passing.  He pointed out that
he was running in read/write mode, and it was atime updates causing
the trouble.  Sure enough, dropping "-w" from fsstress locked me up
too.  Change this so we get better (and more realistic) coverage.
