050: update inode softlimit output

050: update inode softlimit output

With Mitsuo Hayasaka's kernel patch "xfs: change available ranges of softlimit
and hardlimit in quota check", xfs quota behavior is slightly different.

This needs to be reflected in test 050.  The new behavior is that we only start
the timer when we're above soft inode quota, and we don't start the timer when
we're at or below.
