fuzzy: increase operation count for each fsstress invocation

For online fsck stress testing, increase the number of filesystem
operations per fsstress run to 2 million, now that we have the ability
to kill fsstress if the user should push ^C to abort the test early.
This should guarantee a couple of hours of continuous stress testing in
between clearing the scratch filesystem.
