kvm: x86: memset whole irq_eoi
[ Upstream commit 8678654e3c7ad7b0f4beb03fa89691279cba71f9 ]
gcc 7 warns:
arch/x86/kvm/ioapic.c: In function 'kvm_ioapic_reset':
arch/x86/kvm/ioapic.c:597:2: warning: 'memset' used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
And it is right. Memset whole array using sizeof operator.
