kstat_irqs is unsigned int and the return type of kstat_irqs() is also unsigned int so sum should be unsigned int as well even if the result is correct due to automatic type conversion.

This also helps make static code checkers happy.
Patch was compile tested with x86_64_defconfig
Patch is against 4.1-rc1 (localversion-next is -next-20150501)
