The unsigned expression compared with zero `target < 0' is
unneeded and its result is always false. we can also check the
target's value returned from `kvm_target_cpu' is one of the
KVM_* macros, and these macros are defined greater than or equal
to 0.
Therefore, the comparison code block:
if (target < 0)
return -ENODEV;
is unneeded. We can safely remove it.
