Subject: [PATCH] genirq: fix type inconsistency

The return type of kstat_irqs_usr() is unsigned int and kstat_irqs() also
returns unsigned int so sum should be unsigned int here as well.

While it would go trough two automatic type conversions and thus the result
would still be correct it makes static code checkers happy if types match.

Patch was compile tested with x86_64_defconfig 

Patch is against 4.1-rc1 (localversion-next is -next-20150501)
