Miaohe Lin bd0173761a KVM: apic: avoid calculating pending eoi from an uninitialized val
commit 23520b2def95205f132e167cf5b25c609975e959 upstream.

When pv_eoi_get_user() fails, 'val' may remain uninitialized and the return
value of pv_eoi_get_pending() becomes random. Fix the issue by initializing
the variable.
