scheduler: calculate max disk usage based on user prefs correctly.

[davidpanderson]

If max_used_gb or max_used_pct are zero (in client prefs) treat as "no limit".

I haven't tested this.

@lfield, would be nice if you could take a look

This branch has been built and the updated cgi binary has been updated for our Dev project.

[lfield]

It seems to be working fine on LHC@home dev. I am not sure how to test the actual fix as we don't have tasks requiring over 100GB of disk.

[Vulpine05]

This may be a dumb question, but is it possible to generate a task with a lot of bloat to get to 100 gb? Probably easier said than done.

[lfield]

I updated the template of one of our apps so that rsc_disk_bound is greater that 100GB. This is reflected in the WU description.

Max Disk Usage | 104,904.17 MB

In the client I first set the 'Use no more than' option to 10GB and no task was received. I then set this value to zero and received a task. The client is shown bellow.

@lfield, thank you for testing this. I believe now you can merge it
