Ideally this header could be included without the CONFIG_FAULT_INJECTION and it would take care itself for the includes it needs. So, let's temporary workaround this by moving this below and including only when CONFIG_FAULT_INJECTION is selected to avoid build breakages. Another solution would be us including the linux/types.h as well, but this creates unnecessary cases.
