accel/kvm: Check ioctl(KVM_SET_USER_MEMORY_REGION) return value

kvm_vm_ioctl() can fail, check its return value, and log an error
when it failed. This fixes Coverity CID 1412229:

  Unchecked return value (CHECKED_RETURN)

  check_return: Calling kvm_vm_ioctl without checking return value

Reported-by: Coverity (CID 1412229)
Fixes: 235e8982ad3 ("support using KVM_MEM_READONLY flag for regions")
