Bug 24829: ClaimReturnedWarningThreshold is always triggered if patron has one or more claims

ClaimReturnedWarningThreshold is supposed to display a warning if a patron has more than the number of claims specified in the system preference. Currently the warning is displayed for any number of claims over zero.

Test Plan:
1) Make 3 return claims for a patron
2) Set ClaimReturnedWarningThreshold to 4
3) Note the claims warning displays for the patron on circulation.pl
4) Apply this patch
5) Reload circulation.pl, the warning should go away
6) Set ClaimReturnedWarningThreshold to 2
7) Reload the page, the warning should reappear
